Comparison between the evanescent model, the polynomial model and the polynomial including effective conducting path effect (ECPE)

We present a comparative study of submicronic MOSFET characteristics using analytic models of electrostatic potential in the channel. We are particularly interested in the surface potential, threshold voltage, swing and DIBL using the polynomial model with and without ECPE and the evanescent model to analytically express the electrostatic potential. The results show a good agreement between the polynomial model including ECPE, the evanescent model and measures done by simulation tools.
