Low Power and High Gain Double-Balanced Mixer dedicated to 77 GHz Automotive Radar Applications

Abstract : In this paper, we present a mixer implemented in a 130 nm BiCMOS technology dedicated to 77 GHz automotive radar applications. The architecture is based on a double-balanced Gilbert cell with integrated transformer-based Baluns. Interconnections between devices, capacitor accesses and Tee-junctions are modeled using EM software in order to improve the simulation accuracy. The measurement results of the circuit exhibit a conversion gain and a SSB noise figure of 18.5 dB and 13.8 dB respectively over a 74 to 81 GHz band. Supplied under 2.5 V the power consumption is 80 mW and the ICP1 is -13 dBm. The transformer-based Balun allows a good input matching at the RF input port over a 16 GHz range from 72 to 88 GHz
