Cgs and Cgs vs Vgs

anhnha

 Hi.
I set up this circuit for simulation Cgs and Cgs as Vgs changes.

 

Below are the curves Cgs and Cgs vs Vgs.
(please see it in the second post. The forum doesn't allow to post two images in a single post)

I have some questions, hope you can help.

1. Why Cgs and Cgs are negative?
2. Why Cgs and Csg are not equal?
Thanks.

  • Try this instead. It contains the same information. However, in general you should be able to access Cadence Online Support if you're a customer on maintenance - if you are from a university, there is a mechanism via whoever is running the university programme at your university (it depends on the region you're from precisely how that works).
