Abstract
A fully integrated 0.13-μm CMOS receiver front-end for UWB applications is implemented. This receiver enables 8 bands of operation covering 3.1 to 9.0 GHz and consists of a zero-IF receive chain. The shunt-series feedback LNA provides a receiver noise figure of 7.1 to 9.5 dB over 6 GHz bandwidth. The mixer, based on folded-cascode topology, also implements a 3-stage variable gain amplifier and a 1-stage fixed gain amplifier. The average conversion gain and input P1dB are 67.3 dB and -25.4 dBm, respectively. Fabricated die has been bonded and packaged on PCB for measurement. The receiver front-end chip draws 48 mA from 1.2 V power supply. ©2009 IEEE.
