An RF frontend circuit design of a Compass and GPS dual-mode dual-channel image rejection radio receiver

This paper introduces a fully integrated low power consumption radio receiver frontend circuit for a Compass（Beidou） and GPS dual mode dual channel system with 2.5 dB NF,1.02 mm~2 areas,and 8 mA of current in 0.18μm TSMC CMOS process.Except for a few passive components for input matching,other compo...

Summary:This paper introduces a fully integrated low power consumption radio receiver frontend circuit for a Compass（Beidou） and GPS dual mode dual channel system with 2.5 dB NF,1.02 mm~2 areas,and 8 mA of current in 0.18μm TSMC CMOS process.Except for a few passive components for input matching,other components such as an off-chip low noise amplifier or a balun are not required.With a non-tunable passive image rejection filter,the receiver frontend can achieve around 60 dB gain and 34 dB image rejection.
