A Current-Based MOSFET Model

This paper describes a current-based MOSFET model, which consists of simple, continuous, and accurate, single-piece expressions, valid for all regions of operation. This model preserves fundamental properties, such as charge conservation and the source-drain symmetry of the MOSFET, and only a small set of parameters is required to describe it. The accuracy and scalability of the model are certified by the measurements of the transconductance-to-current ratio for different technologies, dimensions and gate voltages. The design of a common-source amplifier illustrates the application of the current-based MOSFET model.
