Hi. I receive an error message once simulating in PSPICE. I have attached a file that explains the problem in details. Will be glad to know the source of the problem.
Thanks! :redface:

Write "VTO" instead of "VTP" and "VTN" for both nmos and pmos.
VTO = -1.5 for pmos and VTO = 1 for NMOS
 
Also KN can not be accepted as model parameters. Change it to KP.

KP is automatically regarded as Kn in NMOS.
 
Thanks a lot! you've really helped me :smile:
 
No Problemo ! Post any problem related circuit simulators and I'll be glad to answer.
