Abstract :
A simple, accurate and universal relationship between MOSFET drain current in saturation, effective channel length, and gate drive has been found. It can be explained by a simple analytical model, whose validity is supported by numerical simulation. The model shows that the length of a velocity saturated region is a crucial parameter for describing MOSFET performance, particularly for short channel devices. The shrinkage of the length deteriorates the merit of channel length scaling
