Abstract:  In this research paper, a high linearity CMOS LNA with source degenerate topology followed by cascode topology is presented. The circuit is implemented on ADS using TSMC 45nm technology using Intermodulation distortion technique for RF front end applications. The LNA is having S11=-70.841dB, S12=-41.067dB, S22=-28.018dB, S21=14.072dB and NF =4.060dB from a 1V power supply and the circuit is having an IIP3=9dBm at 2.4GHz frequency.

Keywords: LNA, Cascode topology, Source degenerate topology, Intermodulation distortion Technique.
