Abstract

A general approach to derive the current-voltage characteristics both for field-effect and bipolar transistors has been proposed based on exact solution of current continuity equation in diffusion-drift approximation taking into account nonuniformity of electric field and charge density distributions between the contacts. This approach describes in a unified manner both linear and saturation parts of MOSFET’s I-V characteristics as for velocity saturation and for electrostatic pinch-off effect cases. It was shown also that the same design formula is appropriate for description of I-V characteristics in bipolar transistors.
