PROJECT TITLE :

Experimental 2.4 GHz CMOS RF front-ends for non-contact vital-sign sensing

ABSTRACT:

A a pair of.4 GHz CMOS front-ends for non-contact very important-sign sensing including respiration and heartbeat is presented. The sensor using one circulator and one differential oscillator not solely achieves the injection-locked function however also reduces the system complexity. Moreover, the injection-locked signals are then down-converted by a phase demodulator constituted by a lumped power divider and a mixer. Finally, the signals are bandpass filtered and amplified for subsequently performing the very important signals. Underneath total power consumption of 32 mW, the respiration and heartbeat data will be recognised correctly up to one.two m far from the subject.
