Abstract
A direct by-inspection method for the derivation of signalflow graphs (SFGs) for multiphase stray-insensitive switchedcapacitor (SC) networks is presented. Compared to our method, others are relatively complicated and not direct in the sense that they require intermediate steps. The multiphase analysis presented here is a generalisation of the method shown previously, where a by-inspection signal-flow graph analysis of biphase SC networks is described. Whereas only a brief summary of the derivation rules and an example are given here, the underlying theory will be published elsewhere.Keywords
