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 Op–Amp Circuits Manual. Including OTA Circuits
: OTAs feature an additional terminal for amplifier bias current ( IABCcap I sub cap A cap B cap C end-sub : Because the output can be "turned off"
). This terminal allows the user to electronically adjust the amplifier's transconductance ( ), effectively providing a way to program the gain. Op–Amp Circuits Manual. Including OTA Circuits
