摘要: This paper presents possible solution of fractional-order high-pass filter (FHPF) with electronically adjustable order between 1 and 2 also pole frequency. It is based on well-known Follow-the-Leader Feedback (FLF) topology adjusted for utilization operational transconductance amplifiers (OTAs) current (ACAs). 3rd-order used in to approximate FHPF response particular frequency band interest. Design supported by Pspice simulations three values the filter's (1.25, 1.5, 1.75) several Moreover, simulation results two different approximations are compared.
