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 freebase: 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.

Thus, it is a voltage controlled current source VCCS. You may select the license of your choice. Width Height 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.
Description Operational transconductance amplifier symbol. 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. From Wikimedia Commons, the free media repository.
Operational transconductance amplifier yago-res: Operational transconductance amplifier dbpedia-de: Por lo tanto, es una fuente de corriente controlada ce 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.
You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
