Abstract :
This work examines the practical issues concerning the realization of switched-capacitors video-rate finite-impulse response filters based on standard CMOS technology. The capacitor spread/sensitivity tradeoff is explored for a number of architectural solutions and an architecture suitable to the challenges of the video field is identified. The nonidealities of switches and operational amplifiers, which must be accounted for at video-rate, are analyzed and practical solutions to prevent performance deterioration are proposed. The implementation of a concrete design case is discussed and presented as a demonstration of the technological solutions proposed
