plotting gm/id vs (id/(w/l))

YasserQG

Hello, 
I want to plot gm/id vs (id/(w/l)) for a simple CS amplifier.

I can plot the gm/id vs Vgs , but I don’t know how to do that for id/(w/l). 

Could anyone please how to plot gm/id vs (id/(w/l)) 

Thank you.

  • This question seems to get asked (or variants of it) rather frequently - there are lots of similar questions on the forums (try searching using the magnifying glass in the top right corner).

    What are you sweeping? If you can plot both gm/id vs Vgs and id/w/l versus Vgs, you can use the Right Mouse Button menu over the x-axis in ViVA to pick which of the two curves you've plotted that you want to be the x-axis.

    Regards,

    Andrew.
