PSPICE error message when simulating CMOS inverter circuit.

AI Thread Summary
The user encountered an error while simulating a CMOS inverter circuit in PSPICE and sought assistance. Key solutions included changing "VTP" to "VTO" and using "VTN" for both NMOS and PMOS, with specific values of VTO set to -1.5 for PMOS and 1 for NMOS. Additionally, the parameter "KN" should be replaced with "KP," as KP is automatically recognized as Kn in NMOS. The discussion emphasizes the importance of correct parameter naming in circuit simulations. The user expressed gratitude for the help received.

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.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
