Noise and IM3 Harmonics Cancelling in Two-Stage Wideband Differential LNA

This manuscript gives a cancelling technique for noise and IM3-harmonic for two-stage differential-low noise- amplifier (LNA). The noise-figure and IM3-distortion is reduced by adopting first-stage with cross-coupled boosted push-pull amplifier. The thermal noise and IM3 which are generated from first stage is cancelled by adopting second stage. The proposed low-noise-amplifier having a 15-17 dB of gain in a 0.1-2.6 GHz of wide-bandwidth by consuming 12 mW with a power supply of 1.3 V. The noise-figure is 1.5-2.6 dB, IIP3 is -3 to 0 dBm and IIP2 is 17 to 21 dBm are achieved. The proposed low-noise-amplifier is designed with 65 nm CMOS technology and 0.009 chip area.
