Abstract
A low supply voltage and highly linear subthreshold CMOS low noise amplifier (LNA) for 2.4 GHz wireless sensor network applications is presented in this letter. We applied multiple gated transistor (MGTR) technique in subthreshold region to compensate the linearity degradation of low supply cascode topology. Moreover, the feedback capacitor, C~f~ is used to enhance the power gain of amplifier without additional dc‐power dissipation. The proposed LNA has gain of 13.1 dB, noise figure (NF) of 3.8 dB, and −2.5 dBm IIP3 while dissipating only 0.49 mW from 0.7 V supply. The LNA has been designed using a 0.13 μm 1P8M standard CMOS process with top metal thickness of 3.3 μm__.__ © 2009 Wiley Periodicals, Inc.
