Hey guys. I'm desigining a circuit that compares the output of an op amp stage to 300 mV DC. When the output of the op amp stage exceeds 300 mV (AC), the comparitor should output 5 V, and when it's below 300 mV the comparitor should output 0 V. For some reason my circuit is outputting 3.488 V and 91.808 mV though. Also, in Multisim, it seems like there's some AC voltage at the output too, which I don't understand / want? Thanks for your help!
