I want to maka a CV plot of MOSFET capacitances. By using ac analysis this is easy. The problem is that i want to keep all dc sources because they are used to bias some other controlling part of circuit. In essense I want to do transient analysis and sweep a dc source at the same time. How is this possible through cadence?
OK, so are you expecting to have a vsin source with a specific frequency, and then have the DC voltage change during the transient simulation. Or do you want to several transient simulations with different DC offsets?
