A Design of 5.8GHz Tunable Band Noise Cancelling CMOS LNA for DSRC Communications

Abstract

This article presents about 5.8GHz noise cancelling CMOS LNA for DSRC communication. The LNA is designed with differential output with balun architecture and resistive-feedback noise cancelling technique. Tunable load capacitor bank achieves wideband input matching and gain selection. The LNA is implemented in 130nm CMOS technology and achieves a simulated gain of 24.2dB and PldB of -13.46dB and noise figure(NF) of 2.74dB at center frequency. The power consumption is 10.51mW at 1.2V power supply. The chip area is 509×559µm2
