  • Abstract
    A low-voltage I/Q downconverter with digital adaptive IIP2 calibration is presented. The system maintains high linearity over time by continuously updating tuning codes in response to varying operating conditions. A prototype is fabricated in a 0.13μm RF CMOS process. At 2GHz LO, it draws 48mA from a 1.5V supply
