Creating a variable capacitor

MaryamHo

Hi,

I am trying to model a triboelectric harvester and I need a variable capacitor for that. To be more specific, I need to model a sinusoidal movement, and use this movement in a capacitor and a voltage source. if I create this sinusoidal movement with Vpwlf, how can I add it to my capacitor and voltage source, or simulate it?

    I do now understand what is meant by "model a sinusoidal movement and use this movement in a...voltages source". However, to create a voltage dependent capacitor whose voltage dependence can be expressed using an equation or table, have you considered creating a verilog-A based model? Mr. Ken Kundert has published a document detailing varactor modeling at his Designer's Guide site entitled "Modeling Varactors". You might consider reviewing that approach.
