A Unified Channel Charges Expression for Analytic MOSFET Modeling

الملخص EN

Based on a 1D Poissons equation resolution, we present an analytic model of inversion charges allowing calculation of the drain current and transconductance in the Metal Oxide Semiconductor Field Effect Transistor.

The drain current and transconductance are described by analytical functions including mobility corrections and short channel effects (CLM, DIBL).

The comparison with the Pao-Sah integral shows excellent accuracy of the model in all inversion modes from strong to weak inversion in submicronics MOSFET.

All calculations are encoded with a simple C program and give instantaneous results that provide an efficient tool for microelectronics users.
