Differential output in cadence

differential output cadence

Hi all

Imagine you have a diff. pair in cadence. The input is diff. and so is the output. You run a transient. How do you see the output of such an amplifier.

Thanks

hi, Sadegh.j

I think that the output is (+output) - (-output).

thanks.

draw the amplifier into some unity-gain configuration, then out~input, and you can check the max.input.range

yeah, but I am still trying to learn how to use the calculator.

do you mean:

VT("/VOP")-VT("/VON")

while /VOP and /VON are the output nets.

yes
