The new DC Bias Model from TDK Corporation enables designers to simulate DC bias characteristics of MLCCs, even when the DC bias applied to the MLCCs varies. The capacitance in the simulation changes dynamically with a changing DC bias voltage, and the new DC Bias Model is available in the HSPICE, LTspice, and PSpice formats.
Because the effective capacitance of high-permittivity MLCCs (Class 2) changes when a DC voltage is applied, the accurate simulation of these MLCCs in circuits must also reflect their behavior when DC bias voltage is applied. For this reason, TDK’s electronic component model is designed to simulate both the frequency and DC bias characteristics of MLCCs. Used together with the DC Super-imposition Model, which enables the simulation of both frequency and DC superimposition characteristics of TDK inductors, the new MLCC tool enhances the accuracy of circuit simulation for power supply circuits.
