Stability and Why It Matters Negative feedback is used in voltage regulators, point-of-load (POL) regulators, voltage references, operational amplifiers (op-amps), and other electronic circuits in order to produce an accurate output in response to an input. In the case of a voltage regulator, the input is an accurate voltage reference and negative feedback is used to compare a sample of the output to the reference. The difference, or error signal, is amplified and used to correct the output. If the feedback loop is stable, then the output converges to the correct voltage. If the feedback loop is not stable, then…
