摘要: This paper presents possible solution of fractional-order low-pass filter (FLPF) with electronically adjustable order between 1 and 2 also pole frequency. It is based on well-known follow-the-leader feedback (FLF) topology adjusted in our case for utilization operational transconductance amplifiers (OTAs) current (ACAs). 3rd-order used to approximate FLPF response particular frequency band interest. Design supported by Pspice simulations three values the (1.3, 1.5, 1.7) several
