In this paper, the indefinite admittance matrix (i.a.m.) method for the analysis of switched-capacitor (s.c.) networks1will be expanded for the analysis of multiphase switched-capacitor (m.s.c.) networks. Such networks comprise active gain elements, capacitors, and switches operated by an arbitrary number of nonoverlapping clockphases. Included as part of this analysis is the derivation of an equivalent-circuit representation of m.s.c. networks which is compatible with classical-circuit theoretical considerations. The analysis method lends itself well to computer processing. A computer algorithm and examples of the proposed method are given.
