WebSep 23, 2024 · if I use an open loop op-amp as comparator, v+ and v− can have significantly different values, so vd=v+−v− wouldn't be equal (or tending) to zero. Yes, that is correct. In order to have vd = 0 (more precise: almost zero) you will need to add a feedback loop with negative feedback around the opamp. – Bimpelrekkie Sep 23, 2024 at 14:18 2
