摘要：
The design of a CMOS 22-29GHz pulse-radar receiver (RX) front-end for ultra-wideband (UWB) automotive radar sensors is presented. Fabricated in a 0.18 mu m CMOS process, the 3mm(2) RX chip achieves a conversion gain of 35-38.1dB, noise figure of 5.5-7.4dB and input return loss less than -14.5dB in the 22-29GHz band. The phase noise of the constituent QVCO is -107dBc/Hz at 1MHz offset from a center frequency of 26.5GHz. The total dc power dissipation of the RX including LO/output buffers is 131mW.
