摘要
A 1.2 similar to 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 mu m 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.
