“How can we control voltage levels using an Op-Amp?”
Op-Amps are great for modifying voltage levels in a circuit. But sometimes things happen during the lifespan of an Op-Amp that can affect how it performs. So how can we design these components to self-regulate? Well, what if we were to connect part of the output circuit to the Op-Amp input. Therefore, the voltage levels would be the same as the input, and any change on one side would affect the other. This technique is known as Op-Amp Feedback and is one of the fundamental concepts of modern circuitry.
