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.

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. 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.

One of its principal uses is in implementing electronically controlled applications such as variable frequency oscillators transcondutcancia filters and variable gain amplifier stages which are more difficult to implement with standard op-amps.

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.
