minimum noise figure vs current that is flowing from drain

Hi guys;

This question is a kind of tool usage, however I could not do it.

My question is:

How can I plot minimum noise figure versus current that is flowing from drain to source. (NMOS device). I can see it NFmin vs Vgs, However I couldnt manage to see NFmin vs Id. Here, I am sweeping Vgs so I am getting NFmin vs Vgs. However, I want to see also Nfmin vs Idrain. How can I put Idrain to the X axis of the graph.

tool: Cadence - RF spectre

any answer? How can I see NFmin vesus Ids at a specific frequency. Is there any way to plot it.

regards.

-> minimum noise figure

you need to keep a current source and model it as variable.
