Abstract :
GSM/DCS1800 direct-conversion transceiver IC with on-chip DC offset calibration system is fabricated on a 0.35 µm SOI BiCMOS process. The IC achieves -107.7 /-19.5 dBm (GSM) and -105.7 /-28.5 dBm (DCS) reference sensitivity and AM suppression performance, respectively, with 112 mA current and 2.8V power supply voltage on receiving mode.
