Can you first simulate transition, to see if the scheme even works?

09/12/2022, 5:07 AMseems like I'm still getting high gain at 1THz, which still makes absolutely no sense

09/12/2022, 5:09 AMmaybe W has weird units?

09/12/2022, 5:09 AMLike not um as it is supposed to be but in meters

Rita
09/12/2022, 5:09 AMidk, I didn't use W anywhere

09/12/2022, 5:10 AMHow do you not use a parameter that exists and is required?

09/12/2022, 5:11 AMW is transistors parameter. Post the screenshot of transistors parameters

09/12/2022, 5:13 AMno i'm saying I didn't use the .param w=0.5

09/12/2022, 5:13 AMhere's one of them

09/12/2022, 5:14 AMokay.
1. The transistors have a parameter W, which might be set to unreasonable values.
2. You may have no load?
Arman Avetisyan
09/12/2022, 5:15 AMidk if the w=4 is wrong. Its suspicious
r
Rita
09/12/2022, 5:18 AMI don't think it is the w=4 because the default transistors have w=1

09/12/2022, 5:41 AM1. then add limited resistance to the gates.
2. Load on the output
