A parametric short-channel MOS transistor model for subthreshold and strong inversion current

A parametric model with short-channel capabilities is presented for MOS transistors. It covers the subthreshold and strong inversion regions with a continuous transition between these regions. The effects included in the model are mobility reduction, carrier velocity saturation, body effect, source-drain resistance, drain-induced barrier lowering, and channel length modulation. The model simulates accurately the current characteristics as well as the transconductance and output conductance characteristics which are important for analog circuit simulation.
