Original Abstract

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