Hi

I am trying to look at the Cgg of a mosfet device. I am using Cadence dsign environment for this.

When I do a dc sweep of the gate under various drain biases (linear/saturation) , how can I plot Cgg against Vgs using the calculator.

I had done this before but using a raw netlist file and running spectre standalone (without Cadence) and it was possible to obtain Cgg as an output parameter.

Any pointers/suggestions would be helpful.

thanks

poor andrew, you have to answer the same question again and again,

hi, do you know the meaning of cgg, cgd, cgs, csg in the bsim3 model? why they are sometimes negative? if i want to manually find out the capacitance at one node, what should i do from the op point?

Ignore previous message I found out how to get all parms.  of individual MOS instances.

thanks
