Synthesis of switched-capacitor circuits simulating canonical reactance sections

A design method is described for switched-capacitor (SC) circuits based on the simulation of doubly terminated reactance filters in canonical tandem section configuration, employing the bilinear -to- - transformation. The SC circuits are completely insensitive to parasitic capacitances. The approach permits the SC realization not only of all types of minimum phase -filters (low-pass, high-pass, bandpass, and bandstop filters with arbitrarily situated finite transmission zeros), which have been described previously but also of -allpasses and nonreciprocal lossless two-ports.
