Abstract :
A 1.2~1.6 GHz low power single-ended input to differential output low noise amplifier for Global Navigation Satellite System (GNSS, such as GPS, Galileo, China Compass, etc.) is proposed in the paper. A new current-reused technique with mismatch adjustment is adopted to achieve low power, low noise factor, high voltage gain and low mismatch simultaneously. The LNA is fabricated in TSMC 0.18 μm RF CMOS process, with only 2 mA current consumption under 1.8 V supply. The LNA exhibits a differential voltage gain of 27-30 dB, a noise figure of 2.4-3.0 dB and gain mismatch less than 0.5 dB.
