A high-temperature physically-based C-infinity-continuous model of low doped accumulation mode SOI pMOSFETs for all regimes of normal operation is presented. The model is based on explicit expressions of the drain current which have an infinite order of continuity. Short-channel effects have been included. The calculated characteristics show good agreement with the measurements for temperatures up to 300 degrees C with smooth transitions between regions of operation. (c) 2006 Published by Elsevier Ltd.
