A Quasi-Two-Dimensional Compact Drain–Current Model for Undoped Symmetric Double-Gate MOSFETs Including Short-Channel Effects

A drain-current model for undoped symmetric double-gate MOSFETs is proposed. Channel-length modulation and drain-induced barrier lowering are modeled by using an approximate solution of the 2D Poisson equation. The new model is valid and continuous in linear and saturation regimes, as well as in weak and strong inversions. Excellent agreement was found with Silvaco-ATLAS simulations.
