#Electronics question: how do amplify <100mV voltages?
I simulated a simple op-amp circuit. It does what I want, with a gain of 15.
But the voltages on +/- inputs differ by 9 mV. And that's about the input offset voltage of a real #opamp ...Is that going to work reliably on a real opamp?
And how do I estimate noise in DC situations?
