A fully integrated 1.6 GHz direct-conversion Doppler radar implemented in 0.25 μm CMOS and BiCMOS technologies successfully detects heart and respiration movement at a distance of 50 cm.
A fully integrated direct conversion Doppler radar using 0.25 μm CMOS and BiCMOS technologies can detect vital signs remotely at 50 cm.
Absolute Event Rate: 0% vs 0%
A fully integrated direct conversion Doppler radar that detects heart and respiration movement at a distance of 50 cm is described. The 1.6 GHz transceiver is implemented in both CMOS and BiCMOS technologies, with each chip occupying 14 mm/sup 2/ using a 0.25 μm silicon processes. The effects on system sensitivity of phase noise at small offset frequencies with range correlation are assessed.
