A Novel CMOS Reconfigurable Mixer for Dual-Mode GNSS Receiver

Abstract:

A Novel CMOS reconfigurable mixer for dual-mode GNSS receiver is proposed in this paper, this mixer consists of a Gilbert mixer with a reconfigurable matching network, it can be used for both USA GPS and China Beidou receiver systems, simulation results shown the configurable mixer has a voltage conversion gain 20.5dB in the interested frequency bands, the S11 parameter is around -18dB at both GPS and Beidou frequency bands, the circuit draws 7.3mA current from 1.8V power supply.
