gm over id
Hi,
I'd like to run basic gm/id methodology on nmos device to extract the plot of ft versus gm/Id, Id/W versus gm/Id, and Id/W versus vgs-vt, etc. But when I plot those relationship in calculator with "OP" operation, it does not show me the right figure (The curse is straight, it seems that cadence only give me one operating point when I sweep the dc Vgs voltage on the mosfet).
Does anybody know how to do this simulation in cadence? or where I am able to find those information?
Thanks you.
