Hi,
I run a simple DC simulation for a single NMOS to get Id-Vds curves, then plot the derivative of the Id-Vds curve to get slope value, it is equal to gds value in simulation output file at strong inversion range; However at weak inversion range or median inversion range, the slope value is 50% or more lower than gds.
Anybody know why?
