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.

Operational transconductance amplifier dbpedia-es: Por lo tanto, es una fuente de corriente controlada por voltaje.


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.

There is usually an amplfiicador input for a current to control the amplifier’s transconductance. Thus, it is a voltage controlled current source VCCS.

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


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. Made with Inkscape SVG electrical symbols. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. 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.
