Abstract:
This paper presents our new developments of Xsim, a unified regional threshold-voltage-based model for deepsubmicron MOSFETs. New features include complete reformulation with bulk reference, including transverse electric field for effective mobility resulting in source-drain symmetry, charge-based AC model fully consistent with DC without the need for C -V data, and inclusion of polydepletion effect for both DC and AC models.
