A novel solution of a fractional order low-pass type frequency filter is presented. The proposed structure comprises of two Double-Output Current Followers (DO-CFs), two Multi-Output Current Followers (MO-CFs) and two Adjustable Current Amplifiers (ACAs). The slope of the transition between the band-pass and band-stop region can be adjusted by intentional control of the order in range from 1 to 2...
This paper presents possible solution of fractional-order high-pass filter (FHPF) with electronically adjustable order between 1 and 2 and also with electronically adjustable pole frequency. It is based on well-known Follow-the-Leader Feedback (FLF) topology adjusted for utilization with operational transconductance amplifiers (OTAs) and adjustable current amplifiers (ACAs). This 3rd-order topology...

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).
