  • Abstract
    A low-power, low-noise direct-conversion 1.8 GHz front-end for WCDMA-type applications features an efficient, robust, digitally assisted self-calibration loop that maintains the IIP2 of the receiver to better than 60 dBm. It has a conversion gain of 38.5 dB, a DSB NF of 2.6 dB, and an IIP3 of -17.6 dBm, consumes 15 mA from a 1.5 V supply, and occupies 1.56 mm2 in a 0.13 ¿m CMOS process.
