Is DC gain "Av0 = gm/gds" always true for weak, median, strong inversion range?

Is DC gain "Av0 = gm/gds" always true for weak, median, strong inversion range?

Q1: Is DC gain "Av0 = Gm/Gds" always true for weak, median, and strong inversion range?

Q2: Is DC gain "Av0 = Gm/Gds" always true for triode(linear), and saturation range?

Hi cqmyg5,

The expression Av=gm*rout is the definition of the intrincin gain of a CMOS device (transistor) and it is fundamental,so it is valid for both cases you numbered above.The evaluation of this expression ofcourse is different for the various inversion levels and ranges of operation.
