I wonder, how to affect the input offset voltage of inverting amplifier when it's output in saturation?
I'm changing gain with decreasing the value of R2. When the gain is greater than 5, output in saturation. But after that point the negative input voltage of opamp also increase with gain increasing.
I cannot limit the value of R2, in this case, how to avoid increasing this offset voltage?
Beacuse I am using virtual ground property of OPAMPs. This offset undesirable for me.
