feedback circuit
21feedback — feed•back [[t]ˈfidˌbæk[/t]] n. 1) elo elm the return of part of the output of a circuit, system, or device to the input, either purposely or unintentionally, as in the reflux of sound from a loudspeaker to a microphone in a public address system… …
22feedback — n. 1 information about the result of an experiment etc.; response. 2 Electronics a the return of a fraction of the output signal from one stage of a circuit, amplifier, etc., to the input of the same or a preceding stage. b a signal so returned.… …
23Audio feedback — (also known as the Larsen effect after the Danish scientist, Søren Larsen, who first discovered its principles) is a special kind of positive feedback which occurs when a sound loop exists between an audio input (for example, a microphone or… …
24control circuit — noun a feedback circuit that subtracts from the input • Syn: ↑negative feedback circuit • Hypernyms: ↑feedback circuit, ↑feedback loop …
25electric circuit — noun an electrical device that provides a path for electrical current to flow (Freq. 1) • Syn: ↑circuit, ↑electrical circuit • Hypernyms: ↑electrical device • Hyponyms: ↑bridge, ↑ …

27Negative feedback amplifier — Figure 1: Ideal negative feedback model A negative feedback amplifier (or more commonly simply a feedback amplifier) is an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.… …
28Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… …
29Regenerative circuit — The regenerative circuit (or self regenerative circuit) allows an electronic signal to be amplified many times by the same vacuum tube or other active component such as a field effect transistor.Description Regenerative circuits were employed in… …
30Current-feedback operational amplifier — Representative schematic of a current feedback op amp or amplifier. The current feedback operational amplifier otherwise known as CfoA or CfA is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage… …
