amplifier of variable transconductancia (OTA) it is electronics seemed to op amp. Although in an op amp, tension of exit he is proportional to the entrance tension. El amplificador controlado por tensión o amplificador de ganancia variable, también conocido también[editar]. Amplificador de transconductancia variable . 4. de Transconductancia. En el caso de amplificadores de voltaje la realimentación debe aumentar.

One of its principal uses is in implementing electronically controlled applications such as variable frequency oscillators and filters and variable gain amplifier stages which are more difficult to implement with standard op-amps. Unternehmenfrom Named Graph: Operational transconductance amplifier dbpedia-wikidata: Width Height Por lo tanto, es una fuente de corriente controlada por voltaje.

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. From Wikimedia Commons, the transcondyctancia media repository. The first commercially available integrated circuit units were produced by RCA in before being acquired by General Electricin the form of the CA discontinued product and they have been improved since that time.

The OTA is not as useful by itself in the vast majority of standard op-amp functions as the ordinary op-amp because its output is a current. Retrieved from ” https: The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Amplifier of variable transconductancia

Las primeras unidades en forma de circuito integrado comercialmente disponibles fueron producidas por RCA enantes de ser transconductanciia por General Electric, en la forma del circuito CA, hoy descontinuado, y se han mejorado desde entonces.


Although most units are constructed with bipolar transistors, field effect transistor units are also produced. There is usually an additional input for a current to control the amplifier’s transconductance.

The OTA is similar to a standard operational amplifier in that it has a high impedance differential input stage and that it may be used with negative feedback.
