Design of Frequency locked loop and Receiver front-end for Burst-Chirp UWB Radar Transceiver for Vital Signs and Occupancy Sensing by monitoring the respiration and heartbeat rate

While there are many technologies and electronic systems used to detect the human vital signs by monitoring the heart beat rate & respiration rate, all these systems rely on physical contact with the human body. Furthermore, each measuring system can only be used for a single person thus increasing the cost and complexity of integrated...

A CMOS Temperature Compensated Log-Amp Detector

Publications of bipolar log-amp detectors for RF power detection show good temperature and RF performance. So far published CMOS log-amps fail to demonstrate accurate performance over temperature. This thesis present a temperature compensated CMOS RF power detector based on the log-amp architecture with an industry temperature range of -40 C to...
