Hi , Can anyone please tell me how to plot lambda vs length for a FET in cadence. I have plotted Lambda vs Vds. How do I carry out the simulation to plot it versus length?

I'd use parametric analysis stepping L, and a DC sweep for
picking off lambda into Calculator; plotting that variable
(vector, implicit) will put it against the parametric analysis
index variable. All you need is the calculator expression for
lambda from Id().
take parametric sweep on L so that the sweep is Id vs L. (to make Id constant W should be a multiple of L, i.e. W=Mul*L)1) Id vs Vds plot (dc sweep of Vds) and take lambda expression into calculator(for which w/L should I take the lambda expression?).
this is basically the answer to (1)2) parametric sweep for different length on same Id vs Vds plot? does it work, because I tried and the it wasn't plotted
from the equation for output resistance, ro=(1+lambda)/(lambda*Id), you can find the expression for lambda and plug it in then plot the output.3) How to plot expression of lambda in calculator against the parametric analysis variable length?
