Abstract: The design of fractional-order filters using Current Feedback Operational Amplifiers as active elements, is presented in this paper.The first step of the procedure is the approximation of the fractional-order transfer function by an appropriate integer-order function and the derivation of the corresponding Functional Block Diagram.As a second step, the implementation of the derived Functional Block Diagram is performed through the utilization of integration and summation blocks constructed from Current Feedback Operational Amplifiers.As a design example, a 1+a order (0<a<1) lowpass filter has been realized and its behaviour has been evaluated through experimental results using the commercially available AD844 discrete IC component as Current Feedback Operational Amplifier.
