Abstract
A fully-active tunable RF bandpass filter is presented. It uses a novel positive feedback RC “Rauch” structure, based on a wideband amplifier for high dynamic range purposes. The filter, designed in a BiCMOS 0.25μm technology, exhibits a 10dBm IIP3 requirement and a 15dB noise figure. The quality factor of 3 obtained from 45 to 240MHz guarantees the required full integration of the selectivity for TV silicon tuners over more than two octaves of the VHF band.
