A 22–29-GHz UWB Pulse-Radar Receiver Front-End in 0.18-$\mu{\hbox{m}}$ CMOS
2009
IEEE transactions on microwave theory and techniques
The design of a CMOS 22-29-GHz pulse-radar receiver (RX) front-end for ultra-wideband automotive radar sensors is presented. The chip includes a low-noise amplifier, in-phase/quadrature mixers, a quadrature voltage-controlled oscillator (QVCO), pulse formers, and baseband variable-gain amplifiers. Fabricated in a 0.18-m CMOS process, the RX front-end chip occupies a die area of 3 mm 2 . On-wafer measurements show a conversion gain of 35-38.1 dB, a noise figure of 5.5-7.4 dB, and an input return
