Towards a true current operational amplifier [CMOS implementation]

Igor Mucha

Abstract

Two true current (current input-current output) operational amplifier structures are described and compared. The first one is a differential-input-single-output device, that fulfills the basic idea about operational amplifiers to provide a high differential gain. The second device is a single-input-differential-output amplifier, that allows one 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.>
