    How does an op amp work?

    I am trying to increase a signal from an oscillator that I built. I can't seem to grasp the concept of how a simple op amp works. I'm hoping somebody will be able to explain it in layman's terms for me.

    The amplifier's differential inputs consist of a non-inverting input (+) with voltage V+ and an inverting input (ā€“) with voltage Vāˆ’; ideally the op-amp amplifies only the difference in voltage between the two, which is called the differential input voltage. The output voltage of the op-amp Vout is given by the equation:

    Vout = AOL (V+ - Vāˆ’)
