Abstract

A single-MOS pole-zero lowpass filter for use in a single-ended-input current-reuse wideband receiver having a stacked RF-to-BB front end adapted to receive and process an RF signal to generate an N-phase BB signal, the lowpass filter being adapted to filter the N-phase BB signal, the lowpass filter having a lowpass input impedance for high stopband rejection at low voltage headroom consumption. The lowpass filter is arranged with one active MOS Mand one self-biased MOS M; Mcreates complex poles and two stopband zeros to boost the stopband rejection; Mprovides BB current-to-voltage conversion and common-mode feedback to alleviate tradeoff between voltage headband and BB gain; and Mis diode-connected to enable the generated BB signal to be copied to a next HR stage.
