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