An analytical fully-depleted SOI MOSFET model considering theeffects of self-heating and source/drain resistance

In this paper, we present a new and analytical drain current model for submicrometer SOI MOSFET's applicable for circuit simulation. The model was developed by using a two-dimensional (2-D) Poisson equation, and considering the source/drain resistance and the self-heating effect. Using the present model, we can clearly see that the reduction of drain current with the parasitic series resistance and self-heating effect for typical SOI devices. We also can evaluate the impact of series resistance and self-heating effects. The accuracy of the presented model has been verified with the experimental data of SOI MOS devices with various geometries
