The is a specialized version of the operational amplifier where the output is a current proportional to the differential input voltage . Unlike standard op-amps that act as voltage-controlled voltage sources (VCVS), the OTA acts as a voltage-controlled current source (VCCS) . 1. Distinguish between standard Op-Amps and OTAs
