Abstract :
This paper presents a carrier-based analytic model for ultra-thin-body silicon-on-insulator (UTB-SOI) MOSFETs. It is based on the exact solution of the Poisson-Boltzmann equation by a carrier approach and the current continuity equation with the back interface oxide layer effect. The mode is valid for all the operation regions (linear, saturation, sub-threshold) and traces the transition between them without fitting-parameters, being ideal framework for UTB MOSFET compact modeling development. We have demonstrated that the I-V characteristics obtained by this model agree with two-dimensional numerical simulations for all ranges of gate and drain voltages
