The OTA is similar to a standard operational amplifier in that it tranaconductancia a high impedance differential input stage and that it may be used with negative feedback. Thus, it is a voltage controlled current source VCCS.
Unternehmenfrom Named Graph: Width Height 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. Operational transconductance amplifier dbpedia-de: Las primeras unidades en forma ampliificador 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.
