Abstract
A circuit simulation model for subthreshold conduction of MOSFET is developed. This model employs a novel interpolation scheme to provide smooth transition from the subthreshold region to the above-threshold region. This interpolation scheme ensures that both channel current and its derivatives (or conductances) are smooth. Since an interpolation scheme is used, a simple, independent, and physically based model can be used for the subthreshold and the above-threshold region. The model is applied to subthreshold conduction for submicron MOSFET. It is also successfully installed in a circuit simulation program.Keywords
