Is there any documentation available for the pygmid library that provides details about the syntax of its functions ? For example, I am looking for guidance on plotting gmid vs gm/gds or other related plots in the function in the library, but I am unable to find the necessary information. @Boris Murmann

I don't think there is such documentation. You could go back to my gm_id starter kit repo and look at the documentation of the original Matlab function that this is based on.
That said, I am not sure I understand the case you mentioned. I think you know how to get a vector for gm_id and gm_gds, so plotting these against each other should not be a challenge.

ok got it Thank you
@Boris Murmann, for example i want to plot "ro", so i want to plot 1/gds (gm/ID), but i don't know how to get the GDS as you can see it returns an empty list

This is not a valid query. There is no usage mode where you can specify a ratio and get an absolute parameter value back. #### Usage mode overview (1) Simple lookup of parameters at some given (L, VGS, VDS, VSB) (2) Lookup of arbitrary ratios of parameters, e.g. GM_ID, GM_CGG at given (L, VGS, VDS, VSB) (3) Cross-lookup of one ratio against another, e.g. GM_CGG for some GM_ID

Copy code
gm_gds = nfet_01v8_lvt.lookup('GM_GDS', GM_ID=10)
print(gm_gds)
