An ultra-wideband (UWB) CMOS low-noise amplifier(LNA) topology that combines a common-gate stage for input wideband matching with a shunt-peaked folded-cascode configuration for wideband amplifying stage is presented in this paper. The proposed UNVB LNA achieves simulated power gain > 10dB from 3.3 to 10.1 GHz with only 0.75 V supply using 0.18 mu m CMOS process. Its broadband matching is better than -10 dB for S11 and S22 from 3.1 to 10.6 GHz, and an average noise figure is about 4 dB, while consuming 11.5 mw with output buffer amplifier.

A 3-8GRz wide-band low noise amplifier with novel input matching mechanism is presented in this letter. The proposed circuit uses transistor's intrinsic capacitor Cgd and only one inductor as input matching network to achieve a measured -10 dB input reflection coefficient from 2.75 GM to 12 GM. The fabricated wideband LNA achieves a measured average power gain (S21) of about 10 dB and noise figure of 3.64-5.5dB from 2.75 to 7.5 GHz.
