Abstract:

A wideband 1.13~1.95 GHz low noise amplifier (LNA) for use in a multimodal GNSS (GPS,BDS and GLONASS) receiver has been implemented in a standard 0.18 μm CMOS process.The LNA achieves a power gain of 10 dB with a noise figure of 2.2 dB,an input match of -10 dB and a P1dB of -5.585 dBm while dissipating 12 mA from a 1.8 V supply.

Key words: low noise amplifier;RF receiver;satellite navigation
