I am running a monte carlo simulation and am observing something inconsistent, think about the design as simple a folded differential amplifier. For a given NFET, on left plot I am showing VGD (DC) in red and Vth in Yellow, both from op in calculator.
On the right plot, I am showing "region" from op, which shows this FET swaps between triode and sat across monte-carlo, though why I see that VGD>Vth for all cases which means I should get triode in all cases and region of 1.
Any idea?
