• low noise amplifier (LNA)
• ultra wideband (UWB)

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 mu m CMOS shows more than 10 dB input return loss, maximum gain of 16 dB, and NF of 3.8 similar to 4.0 dB over the full frequency band while dissipating 5.3 mA from 1.8 V supply.
