A 1.9 GHz double balanced dual gate downconversion mixer in 0.8 /spl mu/m CMOS

Abstract

A low power fully integrated doubly balanced 0.8 /spl mu/m CMOS dual gate downconversion mixer is described. At an RF frequency of 1.9 GHz the mixer has a measured conversion gain of 0 dB, input referred third order intercept point of +2 dBm and a single sideband noise figure of 13.6 dB while consuming 10.2 mA of current from a 3 V power supply.
