A nonlinear capacitor model can be represented in two ways. The fist one defines the "charge on voltage" dependence Q(V) which is used in most cases. For ...
Optimal Charging of Nonlinear Capacitors | Semantic Scholar
Constant-current charging is the optimal solution for charging linear (fixed) capacitors. In this letter, we extend this principle to nonlinear capacitors using a variational method. We address the case where the capacitance depends only on the applied voltage. We show that a nonlinear capacitor stores energy electrostatically and …

We show that a nonlinear capacitor stores energy electrostatically and by another mean, depending on the phenomena behind the variation of the capacitance. We …
Companion Models for Basic Non-Linear and Transient …
2 Non-linear components 2.1 PN Diode As a two-terminal device with only one distinct operating region, the PN diode was a natural starting point for non-linear simulation. The current model does not include parasitic capacitances, but this is planned for the future. The i-v relation describing a diode is the following: i(v) = I S(ev/Vt −1) (1 ...

Simulating the characteristics of SiC MOSFET is of crucial importance to its application. Due to the fast switching speed of SiC MOSFET, accurate modeling of the terminal capacitances is required. In most existing SiC MOSFET models, the drain-source capacitance is considered meticulously, but it is generally modeled by a junction …
Understanding capacitance-voltage nonlinearities in …
Voltage nonlinearity is studied in microelectronic metal / insulator (oxide) / metal capacitors. The influence of electrodes (work function, oxygen affinity) and test parameters (dc or ac bias, frequency) are investigated. A physical model is proposed to explain the capacitance-voltage relation. The model is based on electronic hopping trough oxygen vacancy defects.

Voltage variable capacitor tuning: A review
This paper discusses the history, device theory, characteristics, applications, and future trends of voltage varible capacitor tuning. All equations are stated in terms of two general exponents of power law functions, namely the impurity distribution proportional to xmand the differential capacitance proportional to (V + V 0 )-n. The role of these exponents is shown …
[PDF] Non-Linear Distortions in Capacitors
We have identified one of the major causes of non-linear distortions in capacitors. Charging the capacitor will result in an attractive force acting on the conducting plates. As no material is infinitely stiff, this force will reduce the thickness of the dielectricum and thus increase the capacitance. This process occurs in both phases of an AC ...
Soliton production with nonlinear homogeneous lines
Nonlinear ceramic capacitors are then used to demonstrate high voltage pulse amplification and compression, with the line designed such that a simple capacitor discharge input signal develops soliton trains in as little as 12 stages. Results show some key features that determine efficient production of single and trains of solitons.

Nonetheless, you can use this, with some extra elements, to produce a nonlinear capacitor like you seem to need: Here I used a linear CCCS and a linear capacitor to do the integration of the incoming current and track the charge variable. Then a nonlinear VCVS provides the capacitive behavior of your nonlinear capacitor.
