Fractional-Order Filter Design Employing an Electronically Tunable FOE Based on R-C-NR Topology
Original language description
The paper presents the design of a fractionalorder frequency filter with a tunable Fractional-Order Element (FOE). The FOE is implemented using a distributed Resistive–Capacitive–Resistive with N-times resistance (R-C-NR) layer structure and provides the required phase values with minimal error across a wide frequency band. The structure enables tuning of the parameter alpha in the range from 0.6 to 0.71. The parameters and optimized interconnections of the FOE structure were obtained using genetic algorithms in MATLAB according to the specified requirements. The proposed filter exhibits an lowpass transfer function with an order ranging from 1.6 to 1.71. Furthermore, the cut-off frequency can be tuned within the range of 5 to 100 kHz by adjusting the values of the transconductances. The functionality of the designed filter was verified by simulations in OrCAD PSpice for selected values of the order and cut-off frequency
