So with the following circuit (Q1 and Q2 are matched, as well as Q3 and Q4):
How do I go about calculating the overall small signal gain of the circuit?
So far I am just assuming that since IN- is connected to Vout, this circuit is just merely a voltage follower op amp, so the gain from the differential amplifier (Q1 - Q4) is 1. This means I only need to worry about the gain from Q5 right?
