We are presenting a convergence study of the evanescent model and the polynomial model with and without the Effective Conduction Path Effect (ECPE). These analytic models of the electric potential in the channel are used to analyze the short channel effect for the submicronic Symmetric DG FD SOI MOSFET. In this paper, we figure out the 2D Poisson equation and we analytically write using the evanescent model, the surface potential, the threshold voltage, the DIBL and the sub-threshold swing. The natural scale length for the polynomial model λ_p and its corrected form λ_pc including the ECPE are mentioned. The results, of the analysis of the short-channel effects (SCEs), show a good agreement of the evanescent model and the polynomial model including the ECPE with measures done by simulation tools.
