Synthesis and Analysis of Electronically Adjustable Fractional-Order Low-Pass Filter

Popis výsledku v původním jazyce

A proposal of a fractional (1+a)-order low-pass filter is presented in this paper. The proposed filter operates in the current-mode and it is designed using Multi-Output Current Followers (MO-CFs), Dual-Output Current Follower (DO-CF), Dual-Output Adjustable Current Amplifier (DO-ACA) and Adjustable Current Amplifiers (ACAs) as active elements within the presented topology of the filter. The filter possesses ability to electronically control its order and also the pole frequency by changing the current gain of current amplifiers (ACAs) already present in the structure. Three different values of the order and pole frequency of the proposed low-pass filter were tested as an example. Design of the proposed filter is supported by simulation and experimental results. Simulations of the circuit are carried out in PSPICE simulator with behavioural models of used active elements. The experimental laboratory measurements are performed with help of available devices forming equivalent circuits. Simulations and experimental results of the electronically control of the order and pole frequency are compared in this contribution.
