A 0.1dB NF, 2GHz low power CMOS low noise amplifier

Abstract

Short range applications find significant usage in different areas such as industrial process automation and environmental monitoring. Power consumption and noise figure are important constraint for short range applicaion as it carries limited and irreplaceable power sources. This paper describes a CMOS low noise amplifier (LNA) suitable for low voltage short range application. The reported LNA exhibits the best noise performance when compared with existing circuits. The proposed LNA operates at 2 GHz with noise figure (NF) of 0.1 dB, input and output reflection coefficients are S11, S22 <-10 dB, power gain S21=16 dB and power dissipation of approximately 8 mW from 0.8 V power supply. A standard 90 nm PTM CMOS process is used for simulation.
