Novel earthed capacitor dual-input tunable ideal integrator with enlarged time constant

Abstract

In this communication we propose a new active-RC ideal integrator structure using two operational amplifier active elements. Novelties in the proposed circuit are the realisability of a very large time constant that is independently controllable by single resistor at low sensitivities, dual input capability, and use of a grounded capacitor—a feature desirable for microcircuit fabrication.
