  • Abstract
    A down-converter is presented wherein the IF-output of a mixer is applied to its input transconductor to enhance gain without increasing bias current. A 900MHz receiver with power dissipation of 3.5mW is demonstrated in a 0.13-mum CMOS process. The conversion gain is variable from 10-50 dB, the NF is 9.8 dB at peak gain and the OIP3 is 8 dBV-p. The receiver has a third-order low-pass response at IF. The area requirement is 0.1 mm2.
