Abstract :
A new differential integrator implemented using current feedback amplifiers (CFAs) is presented in this paper. The resulting integrator is stable and does not employ a capacitor in the negative feedback path of the CFA for its operation. Experimental results taken from AD844 CFAs authenticate the viability of the proposed integrator.
