An image-rejection down-converter for low-IF receivers

Implemented in 4.1 mm 2 in 130-nm CMOS, a dual-conversion image-rejection down-converter applied to the wireless code-division multiple-access (WCDMA) standard draws 13 mA from a single 1.8-V power supply. Using an IF of 2.5 MHz, the WCDMA image-rejection band is widened from 0.58-4.42 MHz to 0.48-5...
