Abstract
A method of deriving an equivalent circuit model for a passive component includes a first step of providing a given frequency characteristic of a capacitor, a second step of forming one of an RC circuit, an RL circuit, and an RCL circuit using frequency-independent resistances (R), capacitances (C) and/or inductances (L), as the equivalent circuit model representing a circuit capable of performing a simulation in a time domain, a third step of composing an evaluation function for evaluating accuracy of the equivalent circuit model formed in the second step, and a fourth step of determining values of the circuit components by minimizing the evaluation function composed in the third step. The method with a simulator adapted for implementing this method and a computer-readable storage medium containing a recorded program, derives the equivalent circuit model for a capacitor. The model is capable of performing a simulation in the time domain using a common procedure not dependent upon types of passive components.
