In this chapter we describe and demonstrate techniques for the analysis and design of active switched capacitor networks. Because of their sampled-data character, switched capacitor networks are most conveniently analyzed and designed, in the z-transform domain, like digital filters. However, SC filters are analog networks; thus, the analog concepts of impedance and loading, which are absent in digital filters, are retained. In this chapter a library of z-domain equivalent circuits will be developed to facilitate the analysis, design, and, more importantly, to aid the reader's understanding of switched capacitor networks. With these equivalent circuits, the familiar circuit theory tools, which we use routinely in the analysis of continuous active networks, are extended for use in switched-capacitor networks. Like active-RC networks, there are many SC topologies that can be used to realize a given z-domain transfer function. We will examine some of the more interesting and useful ones.
