21Switching amplifier — A switching amplifier or class D amplifier is an electronic amplifier which, in contrast to the active resistance used in linear mode AB class amplifiers, uses switching mode of transistor to regulate power delivery. The amplifier, therefore,… …
22Phase Linear — articleissues unreferenced=August 2007|Phase Linear was an audio equipment manufacturer founded by Bob Carver in 1970. While primarily known as a power amplifier company it also produced several innovative preamplifers, tuners and the Andromeda… …
23Operational transconductance amplifier — Schematic symbol for the OTA. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op amp, it has two additional biasing inputs …
24Valve audio amplifier — A valve (UK) audio amplifier or vacuum tube (US) audio amplifier is a valve amplifier used for sound recording, reinforcement, or reproduction. Until the invention of solid state devices such as the transistor, all electronic amplification was… …
25Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… …
26Operational transconductance amplifier — Der Operationsverstärker (Abk. OP, OPV, OV, OpAmp, OA) ist ein elektronischer Verstärker, der einen invertierenden und einen nichtinvertierenden Eingang besitzt und eine sehr hohe Verstärkung aufweist. Als Eingangsschaltung wird immer ein… …
27Instrumentation amplifier — An instrumentation (or instrumentational) amplifier is a type of differential amplifier that has been outfitted with input buffers, which eliminate the need for input impedance matching and thus make the amplifier particularly suitable for use in …
28Valve RF amplifier — A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical , typically (but not exclusively) radio frequency signals.Low to medium power valve amplifiers for frequencies below… …
29Audio amplifier — An audio amplifier is an electronic amplifier that amplifies low power audio signals (signals composed primarily of frequencies between 20 hertz to 20,000 hertz, the human range of hearing) to a level suitable for driving loudspeakers and is the… …
30Ultra-Linear — is a term used to describe a type of electronic circuit that is used to couple a tetrode or pentode vacuum tube (also called electron valve ) to a load (e.g. to a loudspeaker).The circuit was developed by Alan Blumlein and patented in 1937 (… …
