چکیده
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 0.18m CMOS process, the RX front-end chip occupies a die area of 3 mm . 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 loss less than 14.5 dB in the 22–29-GHz automotive radar band. The phase noise of the constituent QVCO is 107 dBc/Hz at 1-MHz offset from a center frequency of 26.5 GHz. The total dc power dissipation of the RX including output buffers is 131 mW.

This paper presents a low power impulse-radio ultra-wideband (IR-UWB) receiver based on a reconfigurable, high speed analog correlator called distributed pulse correlator (DPC). The DPC incorporates built-in local template pulse generation, and hence significantly reduces the power consumption and circuit complexity of the analog correlation receiver. A chip prototype of the IR-UWB receiver was...
