Dual-input single-tunable integrators and differentiators using current-feedback amplifier

Some new active-RC integrator and differentiator circuits using the currentfeedback amplifier (CFA) device are proposed; both current-mode and voltagemode versions are reported. The novelties of the designs are dual-input differential capability, single-resistor tunability at low sensitivities and realizability of the pole/zero at the origin. Experimental results are included.
