In this paper, various technological and topological considerations for the design of monolithic MOS switched-capacitor (SC) filtering systems are described. The properties of the passive and active devices typically available in depletion-load NMOS and CMOS technologies are presented as they relate to various SC peformance parameters. Layout techniques for improving specific performance parameters are also given. An overview of MOS operational-amplifier design emphasizes technological considerations in the design of high-performance SC systems. Finally, several important techniques are reviewed for maximizing dynamic range in SC circuits.
