2001/03/01 : Scaling rules MOS Level 903 extended
In new CMOS technologies the dopant concentration varies along the channel due to e.g. pocket implants. Consequently the mobility and thus the gain factor ßsq becomes a function of channel length. To take this effect into account the geometrical scaling rules of the gain factor, the threshold voltage, the drain-induced barrier-lowering and of the first mobility reduction parameter have been adapted. At the same time a quadratic term in the geometrical scaling rules of the body-effect factor has been added.

1998/06/11 : New 1/f noise model in MOS Model 9, level 903
The new 1/f noise model in MOS Model 9, level 903, accounts for the bias dependence of the 1/f component of the input-referred noise. By setting the switch NFMOD equal to 1 the new 1/f noise model is activated, while NFMOD=0 (default) yields the level 902 noise model, in which the input-referred 1/f noise is bias independent. In this way parameter compatibility is maintained.
Note that in MOS Model 9, level 903, also the parameters WDOG and FTHE1 have been placed at their logical position in the parameter list.
