A complete description of switched capacitor networks which include an arbitrary number of non‐uniform input and output phases is presented on the basis of the generalized phase transfer matrix by extending a previously introduced state space approach. the input frequency harmonic (main harmonic) of the periodically time‐varying system transfer function is obtained and the effect of periodic fluctuation of the switching instants on the transfer characteristics of the switched capacitor filters is analysed. This procedure also facilitates the evaluation of the effects of non‐uniform multiphase switching. Application of the results to a switched capacitor filter shows that the frequency response is very sensitive to the fluctuation of switching instants.
