V/sub t/ mismatch does not follow a simplistic 1/(/spl radic/area) law, especially for wide/short and narrow/long devices, which are common geometries in analog circuits. Further, Vt and gain factor are not appropriate parameters for modeling mismatch. A physically based mismatch model can be used to obtain dramatic improvements in the prediction of mismatch. This model is applied to MOSFET current mirrors to show some non-obvious effects over bias, geometry, and multiple unit devices.","PeriodicalId":209025,"journal":{"name":"Proceedings of the IEEE 2002 Custom Integrated Circuits Conference (Cat.
