A 1.227 GHz low power single-ended input, differential output low noise amplifier (balun LNA) for GPS is proposed. A two stage structure with current-reused technique is adopted to achieve low power, low noise factor and high voltage gain simultaneously. The LNA is fabricated in 0.18 ??m CMOS process, consuming only 2 mA current from a 1.8 V supply. The LNA is measured to exhibit a differential voltage...
An ultra-low power wideband CMOS low noise amplifier (LNA) fabricated in TSMC 0.18 mum RF CMOS process for sub 1 GHz applications is presented. The capacitive cross-coupled LNA with forward-body-bias (FBB) technique is adopted to achieve wideband input impedance matching and low power, low noise factor. The LNA is tested in the frequency range of 400-900 MHz, and exhibits a voltage gain of 18.5-20...
