Can anybody help me how to plot C-V curve of varactor. I saw lot of methods to plot which made me bit confused. Want to know the correct one. which analysis we have to do.
Its urgent. Can anybody help me
I am working in cadence environment
Set up a simple s-parameters test bench with DC bias for MOS varactor that is series connect between two PORT components ( don't forget to put necessary DC block caps. and ideal chokes )
Either change the bias only at a single frequency or at some frequency points then read the imaginary part of input impedance.
