I am trying to simulate a pair of NMOS transistors as varactors (BSD connected). However, am not getting any resonance at the particular frequency of interest. When I am simulating it, it is giving a negative drain current with zero transconductance. Also, I want to see the CV curve of this but I am not sure how to do it? Can anybody help me in this?
P.S : I don't know how to add a picture in the comments section so I editing my answer and uploading it here.
