摘要

描述了一种完全集成的直接转换多普勒雷达，可检测距离为50厘米的心脏和呼吸运动。1.6 GHz收发器采用CMOS和BiCMOS两种技术实现，每个芯片占用14 mm/sup /，采用0.25 μm硅工艺。研究了具有距离相关性的小偏置频率下相位噪声对系统灵敏度的影响。

0.25 /spl mu/m CMOS and BiCMOS single-chip direct-conversion Doppler radars for remote sensing of vital signs

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.
