SPICE modeling and quick estimation of MOSFET mismatch based on BSIM3 model and parametric tests

This paper reports a MOS transistor mismatch model applicable for submicron CMOS technologies and developed based on the industry standard BSLM3v3 model. A simple and unified expression was derived to formulate the effect of MOSFET mismatch on drain current variance. A way to quickly estimate the drain current mismatch was also suggested. The model has been integrated into HSPICE, and results obta...
