METHOD AND DEVICE FOR EXTRACTING PARAMETER

摘要

PROBLEM TO BE SOLVED: To provide an environment enabling a precise circuit simulation by precisely extracting the parameter in the equivalent circuit model of a field-effect transistor used for a power converting circuit with a relatively simple method. SOLUTION: In the equivalent circuit model of a field effect transistor used for a power converting circuit, the capacitance Cgs between the gate and the source, the capacitance Cgd between the gate and the drain, and the channel current source Ich are extracted from the switching waveform in the inductive load of the field effect transistor.
