Description

This paper describes a frequency analysis method for linear periodic time-varying (LPTV) circuits. In this method, a linear time-varying equation is approximated as a set of differential equivalentequations using a numerical integration. We propose an efficient method for computing the discretized time-varying transfer functions in terms of many frequency points. Furthermore, computational cost and required memories are reduced by transforming the number of variables for modified nodal analysis into the number of capacitors and inductors in the circuit. We estimate effectiveness of the proposed method by applying it to some examples of SCFs.
