Title: Vsb-clipping effect
Post by 337see733 on Feb 5^th, 2007, 8:57pm

Dear all,

What is purpose of Vsb-clipping in the compact model ? Thanks

I think it's difficult to solve for the surface potential in the face of strong forward Vbs. Note in that case the b-s diode is forward-biased and will generally carry significantly more current than the channel, so minor discrepancies in the surface potential and channel current will be hard if not impossible to detect.

Yes, that clear my doubts. Thanks.
