Can anyone help me with plotting the on resistance of nmos transistor in Cadence when we do dc analysis. I am trying to understand how ron changes with Vgs voltage. How do we do this plot. Any help is appreciated.
Add a save statement into an include file:
save M1:ron sigtype=dev
(where M1 is the instance name of the transistor). Then do your dc sweep, including the file as a definition file or a model file (make sure it has a ".scs" suffix). Then you can access M1:ron from the results browser (in the dc results).
