A Low Noise Amplifier Optimized for a GPS Receiver RF Front End

چکیده
A cascode LNA was optimized for a GPS receiver radio frequency front end using a 0.18 μm CMOS technology. By careful choice of device geometry, gate and source degeneration inductors, a fully integrated LNA can be optimized to have a low noise figure, a high voltage gain and a wide dynamic range. The optimized LNA has a 1.512 dB noise figure, a –42.05 dB S11, a 20.04 dB voltage gain a –19.82 dB input referred 1-db compression point and a –5.49 dBm third order input intercept point, with a 11.6 mW power consumption.
