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 An Entity of Type: 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. One of its principal amplivicador 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.

Por lo tanto, es una fuente de corriente controlada por voltaje.

Operational transconductance amplifier prov: 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.

Thus, it is a voltage controlled current source VCCS. Schematic symbol for an operational transconductance amplifier. Transconducanciafrom Named Graph:
