Abstract:Extension of the gradual-channel approximation is presented with the surface-potential-based MOSFET modeling. All phenomena observed under the saturation condition are described by the potential increase in the pinch-off region in a self-consistent way. The charge induced by the high lateral electric field is demonstrated to become a major contributing factor in the charge distribution of small-size MOSFETs, instead of the conventional intrinsic part. This changes the charge partitioning of the inversion charge, which changes the high-frequency response of small-size MOSFETs as well.
