A two-stage, common-gate in cascade with cascode, ultra wideband low noise amplifier (LNA) topology is proposed for 3.1 to 10.5 GHz full band application. The common-gate first stage is adopted and optimized for low noise figure (NF) at high frequencies. The LNA implemented in 0.18 mum CMOS shows more than 10 dB input return loss, maximum gain of 16 dB, and NF of 3.8~4.0 dB over the full frequency band while dissipating 5.3 mA from 1.8 V supply.
