PSPICE error message when simulating CMOS inverter circuit.

  1. Jan 9, 2012 #1
    Hi. I recieve 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.
