During the last three decades, a large number of new analog circuit building blocks have emerged beyond the well-known operational amplifier, operational transconductance amplifier, Current Conveyors and Current feedback operational amplifier. Among the new building blocks, the operational transresistance amplifier (OTRA) has received considerable attention in the literature. This paper presents a state-of-the-art review of the OTRAs, their bipolar and CMOS implementations and applications in linear and nonlinear analog signal processing/generation along with a comprehensive list of references covering the period from 1992 till date.
