Abstract :
A simple analytical expression to account for electron-velocity overshoot effects on the performance of very short-channel MOSFETs has been obtained. This new model can be easily included in circuit simulators of systems with a huge number of components. The influence of temperature and low-field mobility on the increase of MOSFET transconductance produced by electron-velocity overshoot as channel lengths are reduced can be easily taken into account in our model. The accuracy of this model has been verified by reproducing experimental and simulated data reported by other authors
