Hi everyone;
I am trying to build rectifier circuit using opamp. And I improve understanding and knowledge about that circuit. Normally I expect to see in output half wave rectified signal but seeing full wave rectified signal. When line is in negative interval, the left side opamp trying to equal input and therefore its output go high and diode is reverse biased, opamp lost feedback control. And I think I see in output only divided line signal. What do you think about that comment and can you clarify me about that circuit maybe in positive and negative line interval? And why the left output opamp output is nearly zero volt in line is positive?
