Efficient sensitivity analysis for large nonideal switched capacitor networks

A new sensitivity analysis method in the frequency domain is presented for nonideal switched capacitor networks. The method is more general and efficient than previously published works. There are no restrictions on the number of clock phases, circuit configuration and input signal type (which can be either continuous or sample-and-hold). By performing a substantial amount of frequency-independent preprocessing, and by using adjoint network techniques, the computational costs are reduced, and a highly efficient method results. The method is implemented in a switched capacitor (SC) network analysis program called SCNAP4. Numerical results of the sensitivity analysis of a fifth-order elliptic low pass filter are given
