CAPACITOR CIRCUIT SIMULATION MODEL AND CONSTRUCTION METHOD THEREOF, CIRCUIT SIMULATION METHOD, AND CIRCUIT SIMULATOR

摘要

PROBLEM TO BE SOLVED: To provide a capacitor circuit simulation model capable of satisfactorily representing characteristics of a capacitor and precisely performing a circuit design and a circuit analysis by means of simulation.SOLUTION: A capacitor part replaces a capacitor by a linear voltage control current source. A low pass filter has an action for extracting a DC bias voltage. An operation circuit part performs calculation of circuit equations derived from capacitor equivalent circuits of an ideal C circuit, RC circuit and the like by combining an addition device, a multiplication device and the like. By using the linear voltage control current source, the total voltage applied to the capacitors is applied to an operation circuit. A SPICE model is constituted of those components.
