Abstract

This paper describes the design of a 5 GHz direct-conversion receiver with active DC offset correction targeted at the IEEE802.11a wireless LAN standard and to be fabricated in IBM´s 0.5 μm 50 GHz BiCMOS technology with analog metal option. The receiver has a simulated voltage conversion gain of 25 dB at 5.25 GHz, noise figure of 4.7 dB, IIP3 of -9 dBm, IIP2 of +42 dBm and draws 16.1 mA of current from a 2.75 V supply. The addition of DC offset correction circuitry reduces the differential DC offset voltage to less than 1.5% of the uncorrected offset.
