Abstract

A 24 GHz quadrature receiver front-end in 90-nm CMOS is presented. It consists of a two-stage LNA, passive mixers, and a QVCO. The RF input is single-ended and is converted to differential form in the first LNA stage. The LNA has two bands of operation within the frequency range of the QVCO. The oscillator measures a centre frequency of 23.7 GHz with a 7.2% tuning range, a worst case phase noise over the tuning range of -102 dBc/Hz at 1 MHz offset, and a power consumption of 22 mW. The front-end achieves; 18 dB conversion gain, 8.9 dB NF, -23 dBm ICP1 dB, -11 dBm IIP3, 12 dBm IIP2, and a power consumption of 42 mW (excluding QVCO).
