e/Current-feedback operational amplifier

Information
has gloss	eng: The current feedback operational amplifier or CFA is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback operational amplifier (VFA). The CFA was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103. The first patent covering a CFA is , David Nelson and Kenneth Saller (filed in 1983). The first integrated circuit CFAs were introduced in 1987 by both Comlinear and Elantec (designer Bill Gross). They are usually produced with the same pin arrangements as VFAs, allowing the two types to be interchanged without rewiring when the circuit design allows. In simple configurations, such as linear amplifiers, a CFA can be used in place of a VFA with no circuit modifications, but in other cases, such as integrators, a different circuit design is required. The classic four-resistor differential amplifier configuration also works with a CFA, but the common-mode rejection ratio is poorer than that from a VFA.

Meaning
German
has gloss	deu: Der stromrückgekoppelte Operationsverstärker, auch als Transimpedanz-Operationsverstärker bezeichnet, ist ein Bauelement der Elektronik. Er besitzt einen invertierenden (-) und einen nichtinvertierenden Eingang (+), sowie einen Ausgang, an welchem eine zum Strom in den invertierenden Eingang proportionale Spannung erscheint.

Castilian
has gloss	spa: Un "Amplificador con realimentación" (CFB-current feedback) es un circuito electrónico (normalmente se presenta como circuito integrado) que tiene dos entradas y una salida. La salida es la diferencia de las dos entradas multiplicada por un factor (G) (ganancia): Vout = G \cdot V+ − V- Donde G = \Delta_v = - \fracR_realimentacion}}R_entrada}}
