We have learned, courtesy of Dean Venable, the following method of measuring loop gain, typically in a switchmode power supply, but elsewhere too: A test signal, here called “es”, is injected where ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

Op amps are very-high-gain amplifiers with differential inputs and single-ended outputs. They are often used in high precision analog circuits, so it is important to measure their performance ...

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 ...
