gm/gds , intrinsic gain plot for transistor using spectre/ADEL

Hi All,

sorry but this question might sound awkward but is there a way to directly plot intrinsic gain (gm/gds) of a transistor using ADE-L or running in spectre as a netlist ?

I have a PDK mosfet for which I am trying to generate the gm/gds versus VGS-VTH plots for different gate lengths.

I have a Hspice netlist as an example below , if this equation can be plotted through a Virtuoso schematic and ADE-L that will be great

.lib 'hspice.txt' nominal
