Obtaining Rds from the transistor

wgtkan
Hello:

I have a quick question. What is the Rds (the drain-source) output resistance called in the dc result browser? I see Ron, Rdeff, Rseff, Rgdb? Which one is it?

Is it possible to obtain it from the transistor and during a dc sweep analysis? I was going to save it and plot is vs Vds.

Thank you

    ron (for bsim4) is defined as vds/ids (in the MMSIM12.1 documentation; for some reason this explanation has gone missing in MMSIM13.1, which I have requested to be corrected).

    So my guess is that is what you want.

    Regards,

    Andrew.
