Dear Anirban,

You can design a voltage dependent capacitance by the following relation:

C= K1 +K2 V+ K3 V^2 +

This relation gives a nonlinear relation between the the capacitance C and the voltage V.

K1 represents consatnt capacitance independent of V ,

K2V represents a capacitance which increases linearly with V

and K3V represents a capacitor term which is changes quadratically with the voltage.

Best wishes

Dear Anirban

this is the model you want to use:
