Hello, I have a question I hope someone can shed some light on. The circuit below is meant to be a sample and hold circuit. It will send a voltage to the non-inverting input while a button is pressed. This causes the output to follow the input. Then the button is released and the output voltage simultaneously feeds both inputs in a forever sample and hold. This doesnt work. But why? Output feedback is certainly capable of affecting the input, so why doesnt this work?
