Abstract

A 5.8 GHz radar receiver for non-contact vital sign detection system is designed and implemented in a TSMC CMOS 0.18 μm process technology. The radar receiver integrates variable gain amplifiers and A/D converters on a single chip. In order to make sure the output signal is within the optimal dynamic range, a clutter cancellation mechanism is implemented in the system. Also, null points can be avoided by using I/Q demodulation. Experimental results show that respiration and heartbeats of human subjects are successfully detected in the laboratory environments. The overall power consumption is about 55 mW.
