Post a circuit as a example:
As is know that the ro can be get from vo/io.
I can get vo,in AC analysis.and the ac current of M35 and M36.But i don't know how to get ro.
Because i still cant get the ac current inflow to the output,for the direction of AC current is unkonw.
So i want to know how i can get the output resistence in cadence.Thank you.
