abstract
A 0.18-m CMOS low-noise amplifier (LNA) employing resistive shunt feedback, operating over the entire ultra-wideband (UWB) frequency range of 3.1-10.6 GHz, has been designed, fabricated and tested. The UWB LNA achieves measured power gain of 7.52.5 dB, minimum input matching of -8 dB, noise figure from 3.9 to 6.3 dB, and IIP3 from -8 to -1.9 dBm, while consuming only 9 mW over 3-10 GHz. It occupies only 0.55x0.4 mm 2 without RF and DC pads. With its simple design, miniature size, and competitive performance, this LNA is expected to be valuable for many wireless CMOS UWB receivers. 2011 IEEE.
