Abstract ■

A flexible low power receiver chain based on a wideband front-end in combination with a novel triangular-wave integration sampling baseband section, with strong embedded anti-alias protection, is proposed for multi-mode SDR receivers. The 90nm CMOS receiver operates from 200MHz up to 5.5GHz with a clock-tunable baseband bandwidth from 500kHz to 20MHz. It has 5.5 to 6dB NF, -0.9dBm IIP3 and 20 to 65dB of gain. Current consumption is 14.5mA from a 1.2V supply.
