A passive-matched 22 GHz 2.6-dB-NF CMOS front-end with a 70-800 ps delay block

This paper presents a power-efficient RF differential receiver front-end supporting transmitted-reference (TR) communication in a 90 nm CMOS technology. Particularly, it addresses the issues of designing the frontend amplifier with low-noise and passive matching circuits on a silicon process and integrating a low-power delay unit in the front-end with wideband characteristics. The proposed architecture includes a differential high simulated gain (11 dB) amplifier which is centered at 21.6 GHz (in the K-Band) with a 6.2 GHz bandwidth (18.1~24.3 GHz). The input and output reflection parameters h...
