I know it's not appealing to write one's first post in an RF focused group talking about DC but please bare with me :)
I am interested in plotting some MOS DC parameters like gm, gmoverid, Cgg, gds as they vary across VGS and VDS.
Keeping VDS fixed for the moment, I would expect to be able to DC sweep VGS and get a curve of - say - gm Vs. VGS. This is not the case. I actually get only one point, which is the point corresponding to the "static" value of VGS, in the design variables list.
Of course I could set up an equation in the Calculator for the derivative of Id but I think that "somewhere" the tool should calculate those parameters for me...And also because for some trickier parameters like Cgg the whole process would be more complicated.
The alternative to that is to run a parametric analysis, but this is way less effective timewise.
Does anybody know of a way of overcoming this?
Thank you in advance,
The forum guidelines suggest not posting a question in more than one forum and also not appending to old threads (in general).
So I will answer this via your other post.
