Abstract
(current input - curren output) operational amplifier structures are described and compared. The first one is a differential-input-single-output device, what fulfills the basic idea about operational amplifiers to provide a high differential gain. The second device is a single-inputdifferential-output amplifier, what allows to exploit it as an adjoint element to the differential-input-single-output voltage operational ‘amplifier in current processing circuits interreciprocal to voltage processing circuits.
