I don't understand the three different amplifiers. Are they completely independent of each other?

Hi Ken,
They are driving different nodes of an RC network, so they do affect each other somewhat.
Currently I am using actimes, but with only one amplifier at a time. If I try to analyze all three, then it must be the same AC analysis calculation and all three amplifiers must receive an AC source at the same time. I'd like to use actimes with three different AC analyses where in each one, a different AC source is enabled.
If I analyze one independently or all three at once, I do get different results (second order differences)
Thanks,
Dave
