Design of Crystal-less Transceiver Design
Crystal oscillators become one of the most critical components in wireless communication. However, it limits the size and cost reduction of the overall wireless module. Many applications, e.g., capsule endoscopy, need a complete integration of small-size and cost-efficiency RF transceiver, which cannot afford to employ a bulky external crystal. To realize a miniaturized and low-cost transceiver, the crystal-less transceiver design will be investigated in this project.
TX-to-RX leakage mitigation in radar for vital-sign detection
In radar application, e.g., vital sign detection, the transmitter (TX) and receiver (RX) operate simultaneously. The TX leakage from RX significantly increases the dynamic range of the RX and the complexity of the antenna. A three-port duplexer can separate the RX and TX paths and share a single antenna. In this project, the TX-to-RX leakage issue for radar application will be studied, and the integrated circuits will be implemented.
Broadband RF circuit design for sensing applications
The fast growth of Internet-of-Thing (IoT) enables the easy connection between physical and electrical world. However, this requires lots of sensors embedded around our surroundings, such as our home and our office. The design integrated sensor and its readout circuits capable of operating over very wide bandwidth (i.e., MHz to GHz) are one of the most important research topics for this applications. This project covers the system study of the RF sensors and the circuit design of the key building blocks, such as the oscillator and phase-locked loop.
