I have some errors at my project.Here is the code i wrote for the NMOS :

The errors are:


Missing Model
Expecting keyword STIMULUS,saw Vdc .

Any ideas how to fix it ??

I dont do PSpice; I use free LTSpice. I put your circuit in to the graphics editor in LTSpice, set the parameters, and set up the same simulation as you are trying to do. I works fine in LTSpice.

The netlist automatically generated by LTSpice should work in PSice, so I am posting the netlist. Maybe you can see if that runs, and then correct your netlist appropiately.

ps: I see that this website doesn't allow uploading a .net file, so I had to rename it .txt.
