Abstract

A class AB downconversion mixer for 900-MHz applications is presented. The circuit is implemented in a 25-GHz f_T bipolar process and consumes 10.2 mA total current from a 3-V supply. The design has a power gain of 7.5 dB and operates with supply voltages from 2.7 to 5 V. A single-sideband noise figure of 7.5 dB is achieved by design simplicity, use of bond-wire degeneration in the common-emitter driver stage, and optimization of the device sizes and bias currents. An input 1-dB compression point of -1.5 dBm is achieved by exploiting the class AB behavior of the common-emitter driver stage
