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. Operational transconductance amplifier An Entity of Type: Operational transconductance amplifier dbpedia-wikidata: Operational transconductance amplifier freebase: Thus, it is a voltage controlled current source VCCS.

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. This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. Operational transconductance amplifier dbpedia-es: Schematic symbol for an operational transconductance amplifier.


Although most units are constructed with bipolar transistors, field effect transistor units are also produced. Operational transconductance amplifier yago-res: 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.

There is usually an additional input for a current to control the amplifier’s transconductance. Operational transconductance amplifier dbpedia-it: Made with Inkscape SVG electrical symbols.
