Abstract
In this paper, a circuit building block for realizing an electronically controllable active-only current-mode integrator is presented. The proposed integrator is composed only of an internally compensated type operational amplifier (OA) and operational transconductance amplifiers (OTAs) without needing any external passive elements. The integrator gain can electronically be tuned through the transconductance gains of the OTAs. Some application examples in the realization of current-mode filters employing the proposed current-mode integrator as an active element are also given.
