Recent enhancements of MOS Model 11

摘要

MOS Model 11 (MM11) is a surface-potential-based compact MOSFET model, which was introduced in 2001 (level 1100). An update of MM11, level 1101, was introduced in 2002. At the moment a second update of MM11, level 1102, has been completed and is under test. It includes: i) an iterative solution of the surface potential; ii) an improved description of the velocity saturation yielding a better modelling of the transconductance in saturation; and iii) a better description of noise, especially the induced gate current noise. In this paper we describe these improvements and show the resulting improved modelling of transistor performance.
