Abstract

A holy grail in RF design has been to perform channel selection at RF, i.e., remove strong interferers and even out-of-channel noise at the receiver input rather than in the baseband. Such an approach is attractive for it obviates the need for SAW filters and greatly relaxes the linearity requirements of the receiver chain, ultimately leading to a lower power consumption and a more compact design.

This research demonstrates a universal CMOS receiver employing RF channel selection and meeting the exacting demands of GSM and WCDMA. Drawing upon commutated networks, we introduce the concept of the “Miller bandpass filter” and several of its variants so as to create a receiver that achieves a narrow channel bandwidth and can withstand large blockers. Realized in 65-nm technology, the prototype provides a programmable bandwidth from 350 kHz to 20 MHz and draws 20 mW. The noise figure is 2.9 dB in the absence of blockers and 5 dB with a 0-dBm blocker at 20-MHz offset.
