Hi, I am trying to compare the signal from a current sense circuit to that of a reference voltage to detect no load, then switch the output to a high state through a pull-up. I want to detect when the (-) goes below (+). When the load is removed, there is no current flowing so the voltage drop is zero. The issue is I am creating a feedback loop because I am now trying to pull up the point that I am comparing with initially. This is causing v+ = v-. How can I decouple this?
