The open loop voltage gain as a function of frequency is defined as
(a) AOL(f) = VO/Vin
(b) AOL(f) = VO/Vid
(c) AOL(f) = VO/Vf
(d) All of the mentioned
I had been asked this question in an online quiz.
This is a very interesting question from Open-Loop Voltage Gain as a Function of Frequency in portion Practical Limitations of Op Amp Circuits of Linear Integrated Circuits
