(-11)

If either xj or nsub is zero, the short-channel effects on threshold voltage are not evaluated; that is, F_S = 1.

Drain Saturation Voltage

If vmax is not input, V_DSAT is determined by the pinchoff condition and is given by

(-12)

where

(-13)

(-14)

If vmax is specified, V_DSAT is determined by the velocity saturation effect.

(-15)

where

(-16)

μ_eff is the effective mobility that is defined later.
