Abstract
A field effect transistor having a gate voltage swing in the transistor channel varying as a function of position between the drain and the source. The gate voltage swing in the transistor channel may be made to vary as a function of position by making the threshold voltage a function of position. Alternatively, a split-gate device may be used by applying a voltage between the gates. In both cases, the electric field near the source is raised to accelerate the electrons thereby decreasing electron transit time.
