TLDR
In this article, a nonlinear SPICE model whose static capacity varies with voltage is presented, and the correctness of the model is studied on the capacitive region of the capacitor.Abstract:
As it is known the passive components like the resistor, the coil and the capacitor in reality are not ideal components and have a nonlinear component. In this paper is started from the real equivalent circuit of a capacitor and is created a nonlinear SPICE model whose static capacity varies with voltage. The correctness of the SPICE model is studied on the capacitive region of the capacitor. Also, a study of the behavior of the SPICE model without considering the variation with temperature, aging, ESL and ESR will be presented. All to be considered in a future paper. The behavior of the SPICE model is compared with the behavior of the real capacitor and with the SPICE behavior of the capacitor proposed by the component manufacturer.read more
