Hello,
My query is related to the circuit configuration needed to check unity gain frequency of an opamp. I tried to find and verify(from datasheet) the unity gain frequency of an OPAMP by putting it in inverting configuration with a gain of 20 and then with noninverting configuration with 31 and with another gain so far in these two configurations. Mostly it validates with the datasheet.
Now the query is, is it possible to measure the unity gain frequency with buffer configuration(i.e ideal unity feedback configuration)?
As in the unity feedback case, the maximum gain starts itself from 0dB, remain flats up to certain frequency, and then attenuate. Which location of frequency should we consider to actually refer it as unity gain frequency?
Thanks in Advance.
