It is useful to model the non-ideal characteristics of capacitors, inductors and other passive components by using multi-element "schematics," where each element represents some portion of the device's behavior. Traditional models for these devices suffice for many applications, but the requirements of higher performance equipment, higher operating frequency and faster time to market all drive the need to consider other more sophisticated models. This article reviews the traditional models and then describes an innovative approach to develop more sophisticated ones.
Traditional capacitor and inductor models have consisted of two or three elements (capacitor ...
