Else Kooi Award Ceremony for Masoud Tohidian (Electronic Research Laboratory)

The 2017 Else Kooi Award has been given to Dr Massoud Tohidian during the Award Ceremony at ICT open in Amersfoort on March 22, 2017. The Award was given by professor Bram Nauta (University of Twente), chair of the Else Kooi Award Foundation. Dr Tohidian was granted with the award for his scientific research on high-performance super-heterodyne receivers that are implemented using a minimum of analog circuits.

Masoud Tohidian obtained his PhD in September 2015 at the Electronics Research Laboratory group of the EEMCS Faculty, Delft University of Technology.

The Else Kooi Award is an annual award for young researchers in the field of applied semiconductor research conducted in the Netherlands. The award comes with a prize of 5,000 euros.

Massoud studied high-performance super-heterodyne receivers at the system and architectural level as well as the most critical building blocks at the circuit level. As part of his project, he designed new approaches to especially the bandpass filter, realizing a performance that exceeded the state of the art by a significant margin on several key parameters. Furthermore, he integrated these filters in a flexible super-heterodyne receiver, verifying and demonstrating the performance that can be achieved through this approach.

The jury of the Else Kooi Award concludes that this work is a combination of high quality theoretical analysis, modelling, design and experimental verification at the system, architectural and circuit level, resulting in high performance filters and receivers with a high scientific impact as well as high industrial relevance.

A need to amplify and combine to enable 5G in higher frequencies

Our society's social and streaming behaviour speeds up the need for 5G. Marco Spirito, Daniele Cavallo, Masoud Babaie and Andrea Neto (Microelectronics) are all working on the 'key building' blocks that will enable 5G systems in the near future. Advanced 5G solutions are targeted in the WhALE project (WAtt LEvel transmitters at mm-waves), which is backed by STW. Marco: "And of course, as scientists, we are working on the more challenging building blocks. We are looking for alternative solutions, something that the industry would find extraordinary. The goal is to move to higher frequencies and to transmit, instantaneously large volumes of data. The frequency shift will result in lower available power, which we need to fix with new amplifier concepts. To achieve this there is a need to amplify and combine in this project : smart combining technologies. We are also resourceful in using new 'stuff' like 3D printing in our solutions".


7 July 2016: Opening of CryoLab for Extremely Sensitive Electronic Measurements

The CryoLab of TU Delft's Faculty of EEMCS has been opened on Thursday 7 July by the dean Rob Fastenau. TU Delft scientists from the Tera-Hertz Sensing Group, Jochem Baselmans and Akira Endo, will be leading a team of young scientists and engineers working in the lab on astronomical instrumentation. The first instrument, DESHIMA (Delft SRON High-redshift Mapper), is being developed to be operated on the ASTE telescope in the Atacama Desert in Chile. The goal of the research is to create 3D charts of so-called submillimetre galaxies that, in contrast to 2D charts, also show distance and time.

The large number of superconducting detectors, and the advanced electronics developed at SRON, allows DESHIMA to map a very large volume of space at once. While Endo leads the development of DESHIMA, Baselmans will soon install the next cryostat for testing novel THz array antennas, that will enable his upcoming instrument MOSAIC to target multiple galaxies at once. In the future, the CryoLab is envisioned to also host new coolers from QuTech. Superconducting electronics used for astronomical instrumentation and quantum electronics have much in common, because they both push the limits of what can be observed.


Happy 2016!

Anteverta overgenomen door Maury Microwave

TU Delft spinout Anteverta-mw overgenomen door Amerikaanse Maury Microwave DELFT, 31 maart 2015 - Het Amerikaanse Maury Microwave Corporation, fabrikant van microgolf-meetsystemen en laboratoriumapparatuur, heeft het jonge Delftse techbedrijf Anteverta-mw, spin-out van de Technische Universiteit Delft, overgenomen. Maury Microwave, gevestigd in Californi, neemt Anteverta-mw volledig over. De oprichters van het Nederlandse bedrijf blijven echter wel betrokken bij de verdere ontwikkeling. Wij zullen vanuit Nederland blijven opereren, zegt medeoprichter Mauro Marchetti. Dit is voor ons de ideale stap om verder te groeien. Anteverta-mw B.V. ontwikkelt geavanceerde meetapparatuur waarmee transistors en zenders voor telecommunicatie nauwkeurig geanalyseerd kunnen worden. Ook kunnen de optimale eigenschappen van de zenders worden vastgesteld. Hierdoor kan signaalvervorming in mobiele netwerken tot een minimum beperkt worden, wat een betere dataoverdracht mogelijk maakt, terwijl het energieverbruik sterk verminderd wordt. Het bedrijf werd in 2010 opgericht na een promotieonderzoek van Marchetti en Associate Professor Leo de Vreede (Electronics Research Laboratory) van de TU Delft. Nog voordat er een spin-out werd opgericht, waren er bedrijven die interesse toonden in onze techniek, zegt Marchetti. Met de hulp van het TU Delft Valorisation Centre en Delft Enterprises werden patenten aangevraagd een businessmodel ontwikkeld en de eerste fondsen garant gesteld. Anteverta-mw leverde al snel meetsystemen, hardware en software aan bekende organisaties als het Fraunhofer Instituut en NASA en bedrijven als Freescale en NXP. Delft Enterprises is de plek waar spinout-bedrijven van de universiteit de handvatten krijgen voor een succesvolle start-up, zegt Paul Althuis, directeur Delft Enterprises/TU Delft Holding. Anteverta-mw is een mooi voorbeeld van de manier waarop de TU Delft maatschappelijk en economische waarde creert uit technische kennis. Maury Microwave is blij met de aankoop van Anteverta-mw. Dit is voor ons een essentile stap om onze lange termijn strategie te waarborgen, zegt Michael Howo, CFO van Maury Microwave. Antevertas techniek sluit naadloos aan bij onze productgroepen. Het team, inclusief onderzoekers van de TU Delft, kan ons bovendien verder helpen ontwikkelen. Over Maury Microwave Corporation/Anteverta-mw Maury Microwave Corporation, opgericht in 1957 in Montclair Californi, is marktleider in de productie van RF en microgolf-laboratoriumapparatuur, kalibratiestandaarden en systeemcomponenten. Onze service richt zich op de hele microgolf- en RF-industrie met speciale aandacht voor RF Device Characterization en Automated Tuner Systems.

Microelectronics Colloquium

Material Engineering for Stability Improvement of Perovskite Solar Cells

C.P. Wong
Georgia Tech

Organolead halide perovskites have recently emerged as a fascinating light harvesting material that combines the advantages of simple fabrication process and excellent electronic properties. The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has been rapidly improved from 3.8% to 23.3% within the past several years. In contrast to the stunning rise in efficiency, the instability of the PSCs is its Achilles’ heel. The instability issue of the whole device originates not only from the perovskite layer itself, but also from the use of doped organic charge transport materials, such as spiro-MeOTAD. This talk is to provide material strategies to improve the stability of the organolead halide perovskite materials as well as other functional layers in PSCs. To improve the air-stability of perovskite films prepared from two-step sequential deposition by simultaneously eliminating PbI2 residue and improving the crystallinity of the perovskite films. We developed PbI2 thin films with nano-pores and tunable crystal sizes, which enabled full conversion of PbI2 to MAPbI3. A large perovskite crystalline domains, and that the impurity-free, lead to reduced trap states and improved air-stability of the perovskite thin films. The second part of my talk is devoted to improve the stability of the entire PSC device by developing a solution-processed NiOx hole-transport layer, as the hygroscopic nature of the NiOx film suppresses the diffusion of water molecules to the perovskite, and it is also insusceptible to heat. As a result, the PSCs with a structure of FTO / TiO2 / Perovskite / NiOx / Au demonstrated remarkable air-stability and thermal stability. By further modifying of the NiOx / metal interface by CuSCN, we further realized high-efficiency PSCs with excellent air stability, exhibiting nearly no efficiency degradation after exposed to air for 4 months. Furthermore, the ion migration-induced instability issue through incorporating extrinsic alkali cations (i.e., Rb+, K+, Na+, or Li+) into the perovskite. The size-dependent interstitial occupancy of the extrinsic alkali cations in the perovskite lattice was proposed and verified for the first time through density functional theory (DFT) calculations. Such interstitial doping method suppressed I- ion migration in the bulk of perovskites, thus resulting in reduced I-V hysteresis of the PSCs, weakened poling effects and improved photo stability of wide-bandgap mixed-halide perovskites.

Wideband phased arrays for future wireless communication terminals, Daniele Cavallo (TS group)

Wireless data traffic will grow exponentially in the next years, due to the proliferation of user terminals and bandwidth-greedy applications. To address this demand, the next generations of mobile communication (5G and beyond) will have to shift the operation to higher frequencies, especially to millimetre-wave (mmWave) spectrum (30-300 GHz), that can provide extremely high-speed data links. To enable mm-wave wireless communication, mobile terminals such as smartphones will need phased arrays antennas, able to radiate or receive greater power in specific directions that can be dynamically steered electronically. However, to cover the different 5G mm-wave bands simultaneously (28, 39, 60 GHz, …) and to achieve total angular coverage, too many of such antennas should be on the same device: the main bottleneck is the insufficient space available to place all antenna modules. Therefore, I propose to investigate novel phased array antenna solutions with very large angular coverage and ultra-wide frequency bandwidth, to massively reduce the overall space occupation of handset antennas and overcome the current limitations of mobile terminal antenna development.

Towards smart organs-on-chip, Massimo Mastrangeli (ECTM Group)

Organs-on-chip are microfluidic systems that enable dynamic tissue co-cultures under physiologically realistic conditions. OOCs are helping innovating the drug screening process and gaining new fundamental insights in human physiology. In this talk, after a summary of my past research journey, I will describe how the ECTM group at TU Delft is envisioning the use microfabrication and materials science to embed real-time sensing and actuation in innovative and scalable OOC platforms.

Emerging electronic materials: from lab to fab, Sten Vollebregt (ECTM group)

Due to their nm-size features and often unique physical properties nanomaterials, like nanotubes and 2D materials, can potentially outperform classical materials or even provide functionality which cannot be obtained otherwise. Because of this, these nanomaterials hold many promises for the next generation of devices for sensing & communication and health & wellbeing.

Unfortunately, many promising applications of nanomaterials never reach sufficient maturity to be implemented in actual products. This is mostly because the interest in the academic community reduces once the initial properties have been demonstrated, while the risk for industrialization is still too high for most companies to start their own R&D activities. My goal is to bridge these two worlds by investigating the integration of novel nanomaterials in semiconductor technology and demonstrating the scalability of novel sensing devices. In this talk, I will give examples on how carbon nanotubes, graphene and other emerging nanomaterials can be used in the next generation of sensing devices.

Front-End ASICs for 3-D Ultrasound: From Beamforming to Digitization

Chao Chen

Program:
12:00 - 12:15 Introductory presentation
12:30 - 13:30 Public defense
13:45 - 14:00 Diploma ceremony
Address: Senaatszaal of the Aula Congress Center

SUMMARY
This thesis describes the analysis, design and evaluation of front-end application-specific integrated circuits (ASICs) for 3-D medical ultrasound imaging, with the focus on the receive electronics. They are specifically designed for next-generation miniature 3-D ultrasound devices, such as transesophageal echocardiography (TEE), intracardiac echocardiography (ICE) and intravascular ultrasound (IVUS) probes. These probes, equipped with 2-D array transducers and thus the capability of volumetric visualization, are crucial for both accurate diagnosis and therapy guidance of cardiovascular diseases. However, their stringent size constraints, as well as the limited power budget, increase the difficulty in integrating in-probe electronics. The mismatch between the increasing number of transducer elements and the limited cable count that can be accommodated, also makes it challenging to acquire data from these probes. Front-end ASICs that are optimized in both system architecture and circuit-level implementation are proposed in this thesis to tackle these problems.
The techniques described in this thesis have been applied in several prototype realizations, including one LNA test chip, one PVDF readout IC, two analog beamforming ASICs and one ASIC with on-chip digitization and datalinks. All prototypes have been evaluated both electrically and acoustically. The LNA test chip achieved a noise-efficiency factor (NEF) that is 2.5 × better than the state-of-the-art. One of the analog beamforming ASIC achieved a 0.27 mW/element power efficiency with a compact layout matched to a 150 µm element pitch. This is the highest power-efficiency and smallest pitch to date, in comparison with state-of-the-art ultrasound front-end ASICs. The ASIC with integrated beamforming ADC consumed only 0.91 mW/element within the same element area. A comparison with previous digitization solutions for 3-D ultrasound shows that this work achieved a 10 × improvement in power-efficiency, as well as a 3.3 × improvement in integration density.

On the Relationship between Nyquist Rate and Healthcare: Silicon Systems to Close the Sub-Sampling Gap in Health Screening and Monitoring

Amin Arbabian, PhD (Stanford University)

Abstract
Advances in healthcare technologies have mainly focused on therapeutics, interventional procedures, and “late-stage” diagnostics. These steps have undergone significant improvements, leading to higher survival rates and enhancements in quality of life. Nevertheless, current trends are unsustainable due to the inadequate outcomes on specific critical diseases and skyrocketing national healthcare costs. An important example is cancer, where mortality rates have not seen major improvements, even with the tremendous technological advances in diagnostic imaging tools over the last four decades.

In this talk I will outline our efforts in better marrying technology and healthcare with new systems that 1) enable continuous “Nyquist” imaging and screening to enable preventive/predictive care, and 2) introduce smart implants for precision monitoring and closed-loop therapies. Preventive screening through continuous monitoring has the potential to fundamentally revamp our understanding of disease as well as targeted therapy. Today, the human body is monitored infrequently, perhaps on an annual basis and with a low “resolution”. This is in contrast with advanced electronic systems (many of which our community designs and ships), which are frequently monitored and calibrated. I will summarize a few example projects that aim to address these issues, including portable, semiconductor-based, “Tricorder” imaging systems, ultrasound-powered implantable devices that can measure, detect, and act upon local physiological changes through closed-loop neuromodulation or “electroceuticals”, and finally our new investigation of a noninvasive methods of neuromodulation based on ultrasonic excitation.

Channelization & Classification of Broadband Signals

Ramesh Harjani
University of Minnesota

Our continued desire for increased wireless bandwidth for small and light portable devices have forced the development of novel transceiver architectures that accommodate wideband contiguous and non-contiguous data streams. This talk focuses on the use of discrete time analog signal processing for the development of low power, wideband transceivers for blind modulation classification of signals. Blind signal classification is critical for spectrum surveillance and future heterogeneous wireless networks. This project is a joint collaboration with experts in signal processing, low power VLSI design and analog/RF design. In this talk we will first focus on the analog architectures/tradeoffs for channelizing wideband signals and then briefly describe algorithmic and digital VLSI implementation details. In particular, we focus on hybrid filter banks based on analog FFTs and polyphase FFTs to channelize wideband signals.

    Flexible bioelectronic medicines

    Abstract: Bioelectronic medicines are the next generation of neuromodulation devices: small active three-dimensional neural interfaces able to modulate nerve activity by targeting a specific neural region. They aim to treat a number of conditions, such as diabetes and asthma, in a tailored (per individual) and reversible fashion, avoiding the side effects of conventional drug-based interventions (pharmaceuticals). They achieve so by recording signals from the respective nerves, extracting information and using it as feedback to electrically stimulate the neural region in a closed-loop manner.

    Current technologies for active implants have not yet managed to achieve the miniaturisation and integration levels required for the development of bioelectronic medicines. For such breakthrough devices, novel concepts need to be explored, developed, and tested.

    In this talk I will present my current activities as well as my vision on realizing the first flexible three-dimensional graphene active implant, for safe chronic neural stimulation and recording from the peripheral nerves.

    Cryo-CMOS for Quantum Computing: does it work?

    Quantum computing holds the promise to change our lives by efficiently solving computing problems that are intractable today, such as simulation of quantum systems for synthesis of materials and drugs. A quantum computer comprises both a quantum processor and a classical electronic controller to operate and read out the quantum devices. The quantum processor must be cooled at cryogenic temperature in order to show quantum behavior, thus making it unfeasible to wire thousands of signals from the cryogenic quantum devices to a room-temperature controller.

    While this issue can be solved by placing also the electronic controller at cryogen¬ic temperature, which electronic technology is the best choice for its implementation? This talk will address the challenges of building such electronic controller, and answer whether a standard CMOS technology can be employed for the required analog and digital circuits operating at 4 K and below.

    Advanced Antenna Arrays for Modern Radar and Communication Systems

    Abstract: Several of today’s radar and wireless communication applications are shifting their operation to higher frequency to fulfil more demanding requirements on resolution, compactness and data rates. For this reason, there is a growing need to develop low-cost integrated circuit transceivers working at millimeter and sub-millimeter waves.

    However, on-chip antennas are currently characterized by very poor radiation efficiency and extremely narrow bandwidth. My approach of combining the concepts of connected arrays with artificial dielectrics will solve the inefficiency problem and enable high-efficiency on-chip antenna designs.

    Similar concepts can be also realized at microwave frequencies in printed circuit board, allowing for low-cost phased array antennas with state-of-the-art performance in terms of scan range, bandwidth and polarization purity.

    Imaging with Waves

    We present an overview of our current wave field imaging and inversion research. Effective inversion strategies for important applications in Magnetic Resonance Imaging (MRI), nano-optics, and subsurface monitoring will be discussed. In particular, dielectric shimming (shaping of the radio frequency field in MRI) as well as inversion algorithms that determine the dielectric properties of various tissue types based on measured MRI data will be considered, and state-of-the-art model-order reduction techniques for large-scale wave propagation problems will be discussed as well.


Inverse Problems in Electromangetics

Challenges and New Frontiers

IEEE AP-Sdistinguished Professor Andrea lecturer: MASSA
University of Trento and Director Eledia Research Center

Inverse problems arise when formulating and addressing many synthesis and sensing applications in modern electromagnetic engineering. Indeed, the objective of antenna design, microwave imaging, and radar remote sensing can be seen as that of retrieving a physical quantity (the shape of the radiating system, the dielectric profile of a device under test, the reflectivity of an area) starting from (either measured or “desired”) electromagnetic field data. Nevertheless, the solution of the well‐known theoretical features (including ill‐posedness, non‐uniqueness, ill‐conditioning, etc.) of electromagnetic inverse problems still represents a major challenge from the practical viewpoint. Indeed, developing and implementing robust, fast, effective, and general‐purpose techniques able to solve arbitrary electromagnetic inverse problem still represent a holy grail from the academic and industrial viewpoint. Accordingly, several ad‐hoc solutions (i.e., effective only for specific application domains) have been developed in the recent years

In this framework, one of the most important research frontiers is the development of inversion techniques which enable the exploitation of both the information coming from the electromagnetic data and of that which is provided by prior knowledge of the scenario, application, or device of interest. Indeed, exploiting a‐priori information to regularize the problem formulation is known to be a key asset to reduce the drawbacks of inversion processes (i.e., the its ill‐posedness). However, properly introducing prior knowledge within an inversion technique is an extremely complex task, and suitable solutions are available only for specific classes of scenarios (e.g., comprising sparseness regularization terms).The aim of this talk is to provide a broad review of the current trends and objectives in the development of innovative inversion methodologies and algorithms. Towards this end, after a review of the literature on the topic, different classes of methodologies aimed at combining prior and acquired information (possibly in an iterative fashion) will be discussed, and guidelines on how to apply the arising strategies to different domains will be provided, along with numerical/experimental results. The open challenges and future trends of the research will be discussed as well

Terahertz Sensing group seminar

Design of mm-wave, multifunction ICs for data communication and remote sensing

Prof. Herbert Zirath
Chalmers University of Technology

FLYER OF THE SEMINAR___________
The transmission rate of wireless data in the mobile networks is doubling every year due to the increased usage of mobile multimedia services like streaming video, music, television, data transfer in smartphones and laptop-computers etc. This tendency will require continuously improved telecom infrastructure regarding both base-stations and the backhaul communication links. Today, the E-band (71-76, 81-86, 92-95 GHz) is employed increasingly in the networks, allowing multi Gbps data rate. In a near future however, the E-band will be crowded, and novel, higher frequency bands will have to be employed as well. Several hundred Gigahertz bandwidth is available for new communication and sensing applications just waiting to be exploited at frequencies above 100 GHz. Until now, components for making such ‘THz-systems’ have been too expensive, too bulky, too power hungry and nonsufficient in terms of generating enough power for communication systems. With newly developed RFIC-processes, it is now possible to design multifunctional integrated circuits, realizing a full ‘frontend on a chip’ at frequencies well beyond 100 GHz. Recent results from ongoing projects aiming at enabling new applications for next generation mobile infrastructure, 5G, and security imaging, up to 340 GHz will be reported. So far, critical building blocks such as LNA, PA, VCO, modulator and demodulator, frequency multiplier, power detector and mixer have recently been developed, and results will be reported. Multifunction front-end circuits such as complete receive and transmit RFICs, mixed signal designs for co-integrated baseband/frontend ICs, and radiometer ICs have also been developed and will be reported as well, including the newly developed D-band (110 to 170 GHz) frontend chipset demonstrating state-of-the-art bitrate of beyond 40 Gbps.

    Today, our daily activities are intertwined with the Internet. The ever-growing demand to swiftly get access to the data-cloud systems leads to huge data traffic. In order to seamlessly transmit and receive these gigantic data, _ 40 GB, agile radio-frequency (RF) transceivers are inevitable.

    These radios must be capable of supporting the current and future communication standards such as 5th generation of wireless mobile communications. The ultimate goal is that they can be implemented as universal radios whose modes of operation can be defined by their clients. To address these demands, RF transmitters are currently reinvented and are directed towards digital-intensive architecture. In this short presentation, we will briefly describe the strengths,possibilities, and challenges that exist for these advanced transmitters. First and foremost, the concept of RF-DAC based transmitters will be introduced. Next, the talk will review various RF-DAC based transmitters that have already been implemented at ELCA. Eventually, the presentation will concisely unveil the future directions of the research of these software-defined transmitters at ELCA.

Software defined radio and emerging single-chip radar technology make use of radars in every aspect of life such as autonomous driving, safety and security applications. With the increase of active transmitters, spectrum management and coexistence started to become a concern for some radar systems. In this talk, the previous applications of waveform, frequency agility will be reviewed to bring multi-functionality to the modern radar system. Finally, we will discuss the future research for distributed radar networks and how to fuse data from various radars to acquire different aspects of a target to be viewed simultaneously.

Wireless Power Transfer and Optogenetic Stimulation of Freely Moving Rodents

Farnaz Nassiri Nia

Animal studies are commonly used to test the feasibility and effectiveness of promising novel neuroscience research ideas. One such new technique is optogenetic stimulation, which refers to stimulation of the brain by means of light. Current optogenetic stimulation methods use tethered setups and, typically, the animal-under-study is put into a fixed position. This introduces stress, an obvious reduction in animal welfare, and may thus influence the experimental results. Hence, an untethered setup is highly desirable. Therefore, in this thesis, we propose a complete wireless optogenetic stimulation setup, which allows for full freedom of movement for multiple rodents-under-study in a 40x40x20 cm environment.

This thesis includes a thorough design space exploration and the subsequent development of: an inductive wireless link, a wireless receiver module that resides on the animal, and novel micro-LED array implants.

Radio Frequency Energy Harvesting and Low Power Data Transmission for Asynchronous Wireless Sensor Nodes

Andre Luis Mansano

SUMMARY

Since the Internet of Things (IoT) is expected to be the new technology to drive the semiconductor industry, significant research efforts have been made to develop new circuit and system techniques for autonomous/very low-power operation of wireless sensor nodes. Very low-power consumption of sensors is key to increase battery lifetime or allow for battery-less (autonomous) operation of sensors, which contributes to reducing or preventing the high maintenance costs of battery supplied sensors and reduce the amount of discarded batteries.

This thesis, entitled Radio Frequency Energy Harvesting and Low Power Data Transmission for Autonomous Wireless Sensor Nodes, presents very low-power consumption circuit and system techniques combined with energy harvesting that allow the creation of autonomous wireless sensor nodes. This work focuses on three main challenges:
1) how to improve energy harvesting efficiency,
2) how to minimize power consumption of data transmission and
3) howto combine low-power techniques and energy harvesting in a system.
These challenges are addressed in this thesis with on-PCB and integrated circuit (IC) solutions.

The efficiency of radio frequency (RF) energy harvesting is improved by proposing a new topology of a charge-pump rectifier. The proposed topology uses a voltage boosting network to compensate for the voltage drop in the transistors. The new topology is presented as well as a non-linear circuit analytical analysis. Simulation results are compared to the analytical analysis and measurement results of the circuit that has been fabricated in a 0.18 um CMOS technology and operates at 13.53 MHz. Although the efficiency of RF energy harvesting is improved using the above technique, at the same time, low power techniques in data transmission should be developed to save energy. Pulse width modulation and impulse transmission techniques to minimize power consumption have been developed and are presented in this thesis.

The developed pulse modulation circuitry has been fabricated in 0.18 um CMOS technology as part of a System on Chip (SoC). The new impulse transmitter topology for low-voltage low-power operation has been fabricated on PCB with micro-wave discrete components. Theoretical analysis, simulations and measurements results are shown to prove the impulse transmitter concept.

The circuits developed are integrated in a SoC with energy harvesting to prove the concept of autonomous wireless sensor nodes. Two sensor nodes have been designed and measured: one for autonomous temperature monitoring and the second for autonomous ECG monitoring. Both designs operate from wireless power without the use of batteries.

Finally, the work developed in this thesis is analyzed and future research possibilities are discussed.

Structured electronic design of high-pass ΣΔ converters and its application to cardiac signal acquisition

Samprajani Rout

Abstract:

With the bandwidth of the ECG signal extending from sub-Hz to 200 Hz, a major challenge in developing the analog front-end responsible for digitizing the analog signal for an ECG readout system lies in implementing the large time-constants on chip due to area constraints. While techniques to obtain very large time constants exist, they are heavily limited by both linearity and accuracy, which clearly dictates the need for alternative structures.

In this thesis, a ΣΔ converter is used for its noise-shaping property to digitize the acquired signal. A structured electronic design methodology based on state-space forms is proposed to develop high-pass (HP) ΣΔ converter topologies. As opposed to conventional low-pass or band-pass ΣΔ, a generalized signal transfer function which includes the high-pass characteristic is used. The proposed HP ΣΔ topologies satisfy the signal transfer function, which is high-pass characteristic in this application and the noise transfer function, which is a 2-nd order noise shaping in this case. Furthermore, the noise contribution of each of the integrators is evaluated and the topologies are compared in terms of their total noise contribution. Finally, one of the structures is implemented in 0.18 um technology as a final step of verification.

A 0.6V, 1uW, 0.95µVrms low-power low-noise instrumentation amplifier for ECG/BioZ in 40nm CMOS

Qiuyang Lin

Abstract:

This thesis presents a low-power low-noise instrumentation amplifier designed to be implemented in 40 nm CMOS technology and operating from a 0.6 V supply, intended for use in electrocardiogram (ECG) and bio-impedance (BioZ) signal acquisition. This instrumentation amplifier has one ECG channel, one BioZ channel and allows both signals to be measured at the same time.

The core of the system is an AC-coupled instrumentation amplifier. A DC servo-loop is applied to handle large differential electrode offset (>300 mV) and a positive feedback loop is used to boost the input impedance (>100 MOhms). This instrumentation amplifier achieves low noise (<1 uVrms over a bandwidth of 150 Hz), large CMRR (>100 dB) while only consuming 1 uW of power. The instrumentation amplifier has a noise efficiency factor (NEF) of 2.4 and it occupies only 0.1 mm^2 chip area.

Energy harvesting wireless networks: A new frontier for communication and information theory

Aylin Yener
Pennsylvania State University

Wireless communication networks composed of devices that can harvest energy from nature will lead to the green future of wireless, as energy harvesting offers the possibility of perpetual network operation without adverse effects on the environment. By developing effective and robust communication techniques to be used under energy harvesting conditions, some of the communication devices in a heterogeneous network can even be taken off the grid. Energy harvesting brings new considerations to system level design of wireless communication networks, leading to new insights. These include randomness and intermittency of available energy, as well as additional system issues to be concerned about such as energy storage capacity and processing complexity. The goal of this talk is to furnish the audience with fundamental design principles of energy harvesting wireless communication networks which is an emerging area. The focus will be on identifying optimum transmission scheduling policies in various settings, and the ensuing algorithmic solutions. Time permitting we will also go into the information theory of energy harvesting communications, which brings in new challenges taking into account energy availability and storage at the channel use level.

Physical Foundations Underlying Green Information and Communication Technologies

Earl McCune

There are physical limitations on how much energy efficiency can be realized from any actual hardware used to implement any communications standard. Experience shows that in most instances the signals adopted by the standard committee place an additional ceiling on the achievable energy efficiency using that hardware. For example, there is hardware that is capable of providing more than 60% energy efficiency under ideal conditions, but for some standardized signals the maximum achievable efficiency drops to 7%. This drop in achievable efficiency is predictable, and such analyses should become part of standards committee deliberations. Such a low operating efficiency is not compatible with IoT, 5G, and other upcoming Standards objectives.

This presentation was originally given to the IEEE Green-ICT Initiative Steering Committee at the IEEE Board meeting series in New Jersey on June 16, 2016. It establishes the reasons why such efficiency ceilings occur and shows how to predict them. Further, recipes are provided on how it is physically possible to simultaneously achieve high bandwidth efficiency and optimum energy efficiency along with the PSD impacts that come with these more Green-optimized signal modulations.

Sensor Selection and Bit Allocation in WSNs with Realistic Digital Communication Channels

Hongrun Zhang

For energy management in wireless sensor networks, only the sensors with most informative measurements are activated to operate. How to select sensors that make good tradeoff between performance and energy consumption is what many researchers are focusing on. Existing solutions assume analog data model, i.e., the data from sensors collected by a center node, called fusion center, are analog measurements. In practical application, due to limitations of energy of sensors and bandwidth of wireless channel, original measurements are usually compressed before being transmitted to the fusion center. In addition, transmitted signals are usually distorted by wireless channel effects, therefore it is possible that the received data are corrupted with errors. In this thesis, we consider two compressive techniques: one-bit quantization and multi-bit quantization. In one-bit quantization, an indicator message is generated in a sensor according to whether the original measurement is larger than a threshold or not. In multi-bit quantization, the original measurements are quantized to multiple bits and only the most significant bits are reserved. The indicators or the most significant bits are then transmitted through realistic wireless channel to the fusion center for it to process. By these ways, the transmitted signals are digital, and they may flip into opposite values by the effects of wireless channels. For one-bit quantization case, we develop a sensor selection approach, based on convex programming. For multi-bit quantization, we extend the sensor selection to bit allocation and propose a novel algorithm to determine the number of bits to transmit for each sensors, which is also based on convex programming. In both cases we consider the effects of wireless channels, which are characterized as bit error rate. Particularly, for the multi-bit quantization, numerical results show that the bit allocation can further reduce the cost that we defined compared with existing solutions where transmitted data are assumed to be analog.

Low power digital baseband architecture for wireless sensor nodes

Yuteng Hao

This thesis presents a digital baseband design for an upcoming wireless standards: IEEE 802.11ah. It is a branch of Wi-Fi (IEEE 802.11) standards. Compared with the previous Wi-Fi standards, this new standard has larger coverage range and consumes less energy. It is particularly suited for energy-constrained sensor applications. In contrast to the Digital Baseband (DBB)s of other Wi-Fi standards, this design consumes much less power. The basic modulation method of the system is Orthogonal Frequency Division Multiplexing (OFDM) and the detailed algorithms are explored. To prove the robustness of the system, some error tests for the system are performed. A gate-level hardware design and the synthesis netlist are also presented to prove the low-power design. Based on the synthesis results, a series of optimization is done to lower the power consumption. The DBB has been implemented in 40nm Low-power CMOS process to prove the concept. It includes the key blocks of this system. Measurement results show that the DBB for IEEE 802.11ah is suitable for low power applications. The power consumption of this DBB is around 200 - 400 uW, which is hundreds times less than that of the traditional 802.11 baseband.

Fotios Katsilieris

Defence, March 5, 12.00 Aula, Senaatszaal. Sensor management for surveillance and tracking. An operational perspective. In the literature, several approaches to sensor (including radar) management can be found. These can be roughly grouped into: a) rule-based or heuristics; b) task-based; c) information-driven; and d) risk/threat-based. These approaches are compared in this dissertation and it is found that there is not a single approach that is both Bayes-optimal and takes into account explicitly the user requirements in different operational contexts. In order to overcome the challenges with the existing approaches, this dissertation proposes managing the uncertainty in higher-level quantities (as per the JDL model) that are directly of interest to an operator and directly related to the operational goal of a radar system. The proposed approach is motivated by the threat assessment process, which is an integral part of defence missions. Accordingly, a prominent example of a commonly used higher-level quantity is the threat-level of a target. The key advantage of the proposed approach is that it results in Bayes-optimal sensor control that also takes into account the operational context in a model-based manner. In other words: a) a radar operator can select the aspects of threat that are relevant to the operational context at hand; and b) external information about the arrival of targets and other scenario parameters can be included when defining the models used in the signal processing algorithms, leading to context-adaptive sensor management.

Analysis and Design of High-Speed Successive Approximation Register ADCs

Thanos Ramkaj

HIGH performance Analog-to-DigitalConverters (ADCs) are highly demanded by modern instrumentation, data acquisition and wire-line/wireless communication systems. However, the need for high speed is always accompanied by high power consumption and large area since amplifiers with large bandwidth and analog devices with low noise and high linearity are mandatory to fulfill the stringent requirements of high speed operation. Benefits of technology scaling and the flexibility of digital circuits raise the design challenges towards high gain, low noise and high linearity amplifiers, increasing the difficulty of implementing various ADC architectures with traditional analog techniques. New applications that constantly demand better performance in terms of speed and accuracy, have created a need for energy-efficient ADCs in the GHz sampling frequency and low-to-moderate effective resolution range. The dominantly digital nature of Successive Approximation Register (SAR) ADCs makes them a good candidate for an energy-efficient and scalable design, overcoming the aforementioned challenges, but its sequential operation limits its applicability in the GHz sampling range. It is of great interest to systematically study and understand the trade-offs in realizing such multi-GS/s, low power ADCs.

This thesis work analyzes the trade-offs in realizing SAR ADCs in the GHz range in terms of speed, accuracy, power and area. First, basic ADC principles such as quantization and sampling are discussed and performance metrics are introduced. Then, the theory is summarized and the advantages and disadvantages of various types of ADC architectures for high speed operation are pointed out, while analysis and evaluation of system and circuit level techniques, in order to overcome the speed limitation of SAR ADCs, and extend their operation in the GHz sampling frequency with affordable power and area trade-offs follow. Based on the aforementioned analysis, a novel architecture is proposed to break the speed limit due to sequential operation, and realize an 8-bit single channel 2 GS/s SAR ADC. The proposed architecture combines optimally the multibit/ cycle approach with interleaving comparators. Furthermore, other techniques such as separating the sample and DAC functions, a segmentation switching capacitive DAC with sub-fF unit capacitors and a very lowpower reference generator contribute in speed enhancement and power reduction. The effectiveness and performance of the proposed architecture and techniques is verified through both behavioral modeling (MATLAB, Verilog-A) and transistor level circuit simulations. The sub-blocks composing the ADC such as comparators, DACs, T/H, reference buffers, preamplifiers, biasing blocks, clock drivers are designed in 40 nm digital LP CMOS process and simulation results both for individual blocks as well as for the whole ADC are presented. Simulation results indicate a sample rate of 2 GS/s with an SNDR of 41.8 dB at Nyquist input frequency (1 GHz) and above 35 dB until 10 GHz input frequency, while consuming a total power of 17.2mWat 1.2 V supply.

Receivers Topology Optimization of the Combined Active and WiFi-based Passive Radar Network

Presentation for the EuRAD14 conference

Inna Ivashko

This paper focuses on the accuracy analysis of the combined active and WiFi-based passive radar network. The Cramer-Rao Lower Bound is used as an accuracy metric. It is shown that localization performance of the active radar network can be improved with exploitation of the signals from passive bistatic WiFi radars. This makes reasonable to use information from passive and active radars simultaneously in order to enhance system localization capability. Sparsity-based algorithm is applied to find optimum geometry of the WiFi receivers at the fixed positions of the WiFi access points and active radars.

EI Colloquium

Analog-to-digital converters

Jesper Steensgaard
Linear Technology, Milpitas, CA

Analog-to-digital converters have traditionally been a weak link in mixed-mode signal chains. As such, logarithmic and programmable-gain amplifiers have been used to effectively increase their overall dynamic range. In recent years, however, ADC performance has dramatically improved, making it difficult to design amplifiers and references capable of matching their performance. This talk will discuss the challenges of designing a circuit capable of driving a 20-bit SAR ADC with better than 1-part-per-million accuracy.

Biography

Jesper Steensgaard, obtained his MSEE and then his PhD from the Technical University of Denmark in 1999. He has 20+ years of experience in the design of high-resolution data converters. His early work focused on delta-sigma data converters, including mismatch-shaping binary-weighted-element DACs and continuous-time delta-sigma ADCs. Recently, Jesper developed a family of high-resolution low-power SAR ADCs, including the LTC2378-20, which combine the best features of delta-sigma ADCs (precision, low noise) and SAR ADCs (speed, low power, ease of use).


DIMES colloquium

Probabilistic Design for Reliability in Electronics and Photonics: Role, Attributes, Challenges

Prof.dr. Ephraim Suhir
Portland State University, USA

The recently suggested probabilistic design for reliability (PDfR) concept is based on:1) highly focused and highly cost-effective failure oriented accelerated testing (FOAT),aimed at understanding the physics of the anticipated failures and at quantifying, on the probabilistic basis, the outcome of FOATs conducted for the most vulnerable element(s) of the product of interest and the most likely and meaningful combination of possible stressors (the principle of superposition does not work in reliability engineering), and 2) simple and physically meaningful predictive modeling (PM), both analytical and computer-aided, aimed at bridging the gap between what one "sees" as a result of FOAT and what he/she will supposedly "get" in the field. FOAT and PM based sensitivity analysis (SA) algorithms are developed as by-products.

The PDfR concept is based on the recognition of the fact that nobody and nothing is perfect, and that the difference between a highly reliable and insufficiently reliable product is merely in the level of its probability of failure. If this probability (evaluated for the anticipated loading conditions and the given time in operation) is not acceptable, then such a SA can be effectively employed to determine what could be possibly changed, in terms of materials, geometries, application restrictions, etc., to improve the situation.

The PDfR analysis enables one also to check if the product is not "over-engineered", i.e., is not superfluously robust: if it is, it might be too costly: although the operational reliability cannot be low, it does not have to be higher than necessary either, but has to be adequate for the given product and application. This means that when both reliability and cost-effectiveness are imperative, ability to quantify reliability is a must. In this seminar the major PDfR concepts will be illustrated by case studies and practical examples. Although some advanced and subtle PDfR predictive modeling techniques have been recently developed for quantifying and assuring reliability of electronic and photonic products, especially those intended for aerospace applications, the practical examples addressed employ more or less elementary analytical models.

Long-range 3D Range Detector Based on Time-correlated Single-photon Counting

Dali Zhang

Three-dimensional (3D) range detectors enabling 3D computer vision is now popular in automotive industry. With their participation, automobile safety has been further enhanced, autonomous driving has become realizable. Time-correlated single-photon counting (TCSPC) technique utilizing complementary metal-oxide semiconductor (CMOS) single photon detectors (SPDs) and time-to-digital converters (TDCs) embodies the proper participant of automotive 3D vision, with low power consumption, low cost, high speed, high robustness, small size, and portability.

In this thesis, a TCSPC 3D range detector for automotive application was studied and modeled. The model covered all main components of a TCSPC system, including the TCSPC range detection process, the signal, and the noise. It was designed to predict the behavior of TCSPC systems and help future designers optimize the performance in accordance with the targeted application.

To verify the model, a experimental setup was designed, implemented, and characterized. The setup consists of a data acquisition system, data processing procedures, and an optical-mechanical system. Measurements performed using the setup have confirmed that the model was designed correctly. For further exploration, range detection from 0.2 m to 60 m were carried out.

ISCAS 2014

2014 IEEE International Symposium on Circuits and Systems

Welcome from the General Chairs of the Organising Committee

On behalf of the Organising Committee we welcome you to Melbourne, ranked by the Economist Intelligence Unit in 2011, 2012 and 2013 as the most liveable City in the world, to Australia, and to the 2014 IEEE International Symposium on Circuits and Systems.

ISCAS2014 is sponsored by the Institute of Electrical and Electronic Engineers Circuits and Systems Society (IEEE CASS), and generously supported by the State Government of Victoria and the Melbourne Convention Bureau.

As you all know, ISCAS is the flagship annual conference of IEEE CASS, and it is well established as the worlds premier networking forum in the fields of theory, design and implementation of circuits and systems. As a result of the release of its 2012 Vision and Mission (see ieee-cas.org), the CASS goal is to develop ISCAS also as the leading forum for pioneering circuits and systems contributions to humanitys grand challenges.

Accordingly, the special theme of ISCAS 2014 is nano/bio circuits and systems applied to enhancing living and lifestyles, particularly in relation to the multidisciplinary grand challenges in healthcare and wellbeing, the environment and climate change.

Keynotes

ISCAS2014 has four keynote presentations, two of which address crucial aspects of high priority grand challenges, in health and in sustainability, while the other two describe frontier work at the extreme ends, in terms of scale, of circuits and systems engineering new devices that promise to sustain the remarkable advances in semiconductors that we have enjoyed for over 60 years, and design methods for systems of systems, which are relevant to so many grand challenge problems:

Dr Donald E. Ingber from Harvard University on Monday will present Microengineered Human Organs On Chips, describing advances he and his team have made in the engineering of microfluidic Organs-on-Chipsmicrochips lined by living human cells created with microfabrication techniques that recapitulate organ-level structure and functions as a way to replace animal testing for drug development and mechanistic discovery.

Professor Iven Mareels from The University of Melbourne in his talk on Wednesday, titled Circuits and Systems for Modern Irrigation Management, describes work over 15 years on circuits and systems research, development and commercialisation of an internet-of-things dedicated to smart irrigation water management.

Professor Victor Zhirnov from the Semiconductor Research Corporation, in Scaling Limits of Nanoionic Devices, elaborates how recognition that crystal defects could be used as controllable entities, rather than being seen as imperfections, leads to the possibility that nanoionic resistive switching devices may be scalable down to ~ 1nm and thus may offer a promising path to replace the foundation of todays computing technologies.

Dr. Stephan C. Stilkerich from Airbus Group will present Model Based Engineering of Highly Mobile Systems of Systems: Safe Aeroplanes; Safer Automobiles, with an introduction and post-talk discussion moderated by Dr Graham Hellestrand from Embedded Systems Technology. This keynote deals with front-line approaches to engineering electronic systems and their software, that are required to perform real-time control critical for the safe operation of airplanes and cars, including while operating in dense traffic and simultaneously reducing environmental impact.

Technical Program Regular Sessions

The technical program consists of tutorials, lecture papers, poster papers and demonstrations accepted based on peer review of the submission from regular open calls. We have retained many of the ISCAS features that have evolved in recent years, and added new features, some in response to ISCAS feedback, to continue to improve attendees experience of the event.

We are very pleased to report that ISCAS2014 will be first time that the new CASS Conference App will be made available to all attendees, and we look forward to your feedback to improve it. The CAS Society has supported the development of the Conference App, through Conference4Me, to facilitate the navigation of the conference agenda and venues, secure access to proceedings, micro-blogging, live discussion and ranking of papers, providing feedback to organizers and general improvement of attendees experience at CAS conferences.

Lecture papers follow the traditional ISCAS format. There are nine lecture sessions over three days, with session having 11 parallel streams. Sessions are 90 minutes with up to five papers, allowing 18 minute for each including introduction, presentation and discussion.

The Demonstration session and Poster sessions are held over 3 hours commencing at the 3pm coffee break on Monday, Tuesday and Wednesday. The Demonstration session is Monday only. There are no competing parallel lecture sessions during the first 90 minutes of each days Posters/Demonstrations, allowing increased attention to them from all attendees.

We have increased the length of the lunch break to 90 minutes. This will allow more time for the CASS side meetings, particularly the annual meetings of the 15 CASS Technical Committees, which are playing an increasingly important role in leadership of the Society. The longer break will also provide a more relaxed walk to the nearby restaurants for the lunch break, and we hope it will facilitate a greater level of networking.

Following the ISCAS2013 lead we continue the trial of offering free attendance at Tutorial and CAS-FEST sessions for all ISCAS2014 registrants. We have also expanded both the tutorial program and CAS-FEST. CASS goals in these moves are both to widen the reach of and to increase participation in the tutorial program and CAS-FEST. We will greatly appreciate feedback from attendees on the value you perceive in these offerings.

Tutorials

ISCAS2014 commences on Sunday with 19 half-day and 1 full-day Tutorial sessions.

We have included two Tutorial sessions on Technology Management in response to feedback from CASS industry members:

T19 Interfacing Organisations: How to successfully manage organizational interfaces by Felix Lustenberger; and T20 - Managing Technology Professionals by Tuna B. Tarim: Transitioning from Individual Contributor to Management. Felix and Tuna are CASS members and also leaders of IEEEs Technology Management Council, which was recently approved to transition to an IEEE Society.

Also in response to feedback, from the Women in CAS (WiCAS) and Young Professionals Program (formerly GoLD) groups, is a tutorial on career development, social skills, collaboration and networking:

T7 Engineering Networks that Work: Design Tools for Your Career by Dr Margaret Collins Margaret is a Cardiff-based research consultant, professional coach and trainer with extensive experience in helping people achieve their career goals. Come ready to get involved this is an active workshop session!

A third initiative in the Tutorials is a full day introduction to Memristive devices, circuits, systems and applications, the topic of this years CAS-FEST. This will cover all aspects of this emerging technology, namely: theory, practical nanodevices, physical switching mechanisms, circuits and emerging applications:

T21 If its Pinched its a memristor (AM), Professor Leon Chua T22 ReRAM Memristive Devices: Electrochemical Systems at the Atomic Scale (AM), Dr Ilia Valov T23 Analog and Mixed-Signal Applications of Memristive Devices (PM), Professor Dmitri Strukov T24 Integrating memristive devices in CMOS neuromorphic computing architectures (PM), Professor Giacomo Indiveri The aim of these sessions is to provide sufficient introduction to enable a typical ISCAS attendee to appreciate the state of the art material that will be presented in the CAS-FEST sessions.

CAS-FEST

Since its inception in 2010, the Circuits and Systems Forum on Emerging and Selected Topics has progressively become more closely integrated with ISCAS. This years topic was again selected from an open call and the winning proposal, from members of the Nonlinear Circuits and Systems (NCAS) Technical Committee, has taken still further this level of integration with ISCAS. This includes the presentation of invited introductory tutorials in the regular ISCAS Tutorials program (see above), the inclusion of three Special Sessions in the regular ISCAS Lecture Papers program, a full day of CAS-FEST Special Sessions on Wednesday, and the highlight full day of CAS-FEST Keynote talks on Thursday.

With this additional integration, CAS-FEST 2014 will bring together leading experts and provide a thorough coverage of the field of memristors, from an introduction to those unfamiliar with the field, through solidifying existing knowledge, to highlighting developments at the forefront of the field, and pointing to future challenges and promising directions for research. We hope that this coordinated approach will result in a landmark event in the development of the field.

Social Events and Awards Dinner

We are planning the now standard set of ISCAS evening events, with the Welcome Reception on Sunday evening soon after the conclusion of Tutorials, the WiCAS/YPP (formerly GoLD) event on early Monday evening, the Awards Dinner on Tuesday evening, and the Closing Reception immediately following the last session on Wednesday. Watch out for the Australian twists!

We hope that you will have a rewarding and enjoyable time in Melbourne at ISCAS2014 and look forward to meeting as many of you as we can!

Physical design of a 3D router

Milovan Vasic

With the use of multi-core architectures, the Network-on-Chip (NoC) became an important research topic. The most important benefit of a NoC compared to a communication bus is that it is scalable. The heart of the NoC is the router, which provides the communication between different computational units. This component is highly suitable to be a 3D component, which means that the connection can go into a vertical direction. This way the NoC is extended, with the same area footprint. This thesis describes the physical design of the 3D router, where various design problems are solved. An existing router architecture is used as a start-point. One of the problems which this thesis is trying to solve, is the reduction of the number of needed data lines. This is especially useful for the vertical data lines, which are implemented with Through Silicon Vias (TSVs). A TSV has a large footprint compared to a transistor, which means it takes up a lot of chip area. This results in increased cost. The reduction of the data lines is accomplished by the serialization of the data. It is determined that the best serialization ratio is 4. The 3D router is also adjusted for asynchronous operation. This is accomplished with the use of FIFOs, two-flop synchronizers and Gray Encoders.

OFDM Analysis: an Industry Point of View

Earl McCune

With more than 40 years of experience in wireless communications technology and its associated hardware construction, this presenter finds the current flurry of interest in orthogonal frequency division modulation (OFDM) very interesting. It is surprising that the extremely revolutionary nature of this signal class is actually poorly understood, particularly by the academic community. On the industrial side, there is a general misunderstanding of the economic consequences of building hardware needed to generate and receive an OFDM signal. Here the motivation and physical principles of OFDM are built from fundamental concepts, from which the signal characteristics are evaluated and compared with conventional QAM. Conclusions on the comparative economics of OFDM are drawn.
