A GSM/EGSM/DCS/PCS direct conversion receiver with integrated synthesizer

A global system for mobile communications direct conversion receiver with an integrated synthesizer is implemented with a 0.35-/spl mu/m BiCMOS technology. Proposed second-order intercept point calibration method is analyzed and verified by measurements. The maximum IIP2=66 dBm is achieved by an 8-b resistive calibration code. The receiver draws 57/63 mA from a 2.7-V supply.
