Open loop gain of an operational amplifier

[fickle]

1. The problem statement, all variables and given/known data

How can the open loop voltage gain of an operational amplifier with AC input voltage be determined experimentally?

Supply voltage for op amp is +9V.

2. Relevant equations



3. The attempt at a solution

I'm really stuck here. I would appreciate some outline of basically what I have to do so I could even make a first attempt at this.

An opamp has a very large gain with a DC input, so you must make sure the inputs
are at the same voltage if there's no input signal.

Use feedback to do this at DC without producing AC feedback.
