Abstract: This work presents a continuous, analytic drain-current model for symmetric DG PMOSFETs. The model is derived from the closed form solution of Poisson|s equation and current continuity equation without the charge sheet approximation. The model is extended to include the mobility degradation effect. In addition, a fast solver is presented which determines drain current to within a user-defined accuracy. The new model is fit to hardware, and I–V curves comparing the analytic model to experimental data are shown.

Keywords: DG PMOSFETs; MOSFETs; analytical modelling; drain current models; simulation; calibration; nanoscale technology; nanotechnology; mobility degradation.
