Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… … Wikipedia
Operational 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… … Wikipedia
Isolation amplifier — Articleissues confusing=December 2007 unreferenced=December 2007 orphan=December 2007Isolation amplifiers provide electrical isolation and an electrical safety barrier. They protect data acquisition components from common mode voltages, which are … Wikipedia
Fully differential amplifier — A fully differential amplifier, usually referred to as an FDA for brevity, is a DC coupled high gain electronic voltage amplifier with differential inputs and differential outputs. In its ordinary usage, the output of the FDA is controlled by two … Wikipedia
Common-mode rejection ratio — The common mode rejection ratio (CMRR) of a differential amplifier (or other device) is the tendency of the devices to reject the input signals common to both input leads. A high CMRR is important in applications where the signal of interest is… … Wikipedia
Current-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… … Wikipedia
Common mode rejection (CMR) — A&V A measure of how well a differential amplifier rejects a signal which appears simultaneously and in phase at both input terminals. As a specification, CMR is usually stated as a dB ratio at a given frequency … Audio and video glossary
Superheterodyne receiver — A 5 tube superheterodyne receiver made in Japan around 1955 In electronics, a superheterodyne receiver (sometimes shortened to superhet) uses frequency mixing or heterodyning to convert a received signal to a fixed intermediate frequency, which… … Wikipedia
THD analyzer — Total Harmonic Distortion (THD) Analyzers calculate the total distortion introduced by all the harmonics of the fundamental frequency wave. In most cases THD is the amount that is required to calculate, rather than distortion caused by individual … Wikipedia
