Simultaneous noise and input matched ultra wide band LNA design

Abstract

Proposed a low noise amplifier (LNA) design technique that satisfies simultaneous noise and input matched condition over ultra wide band (UWB) frequency range. Simultaneously, noise- and input-matched UWB LNA is implemented in 0.18 mu m CMOS technology, and measurements show higher than 8 dB of input return loss, maximum gain of 10.5 dB, and noise figure of 3.9-6 dB over 2-4 GHz while dissipating 4 mA from a 1.8-V supply.
