Journal ArticleDOI
Fractional-order circuits and systems: An emerging interdisciplinary research area
TL;DR: A recent article published in this magazine has labeled fractional-order continuous-time systems as the "21st century systems" and highlighted specific problems which need to be addressed particularly by electrical engineers.
Journal ArticleDOI
On the stability of linear systems with fractional-order elements
TL;DR: In this paper, the stability of linear integer-order circuits with one fractional element, two fractional elements of the same order or two fractions of different order is studied, and a general procedure for studying the system with many fractional components is also given.
Journal ArticleDOI
Fractional-Order Sinusoidal Oscillators: Design Procedure and Practical Examples
TL;DR: The Barhkausen condition for a linear noninteger-order (fractional-order) dynamical system to oscillate is derived and the oscillation condition and oscillation frequency of some famous integer-order sinusoidal oscillators can be obtained as special cases from general equations governing their fractional- order counterparts.
Journal ArticleDOI
Construction of classes of circuit-independent chaotic oscillators using passive-only nonlinear devices
TL;DR: In this paper, two generic classes of chaotic oscillators comprising four different configurations are constructed based on the simplest possible abstract models of generic second-order RC sinusoidal oscillators that satisfy the basic condition for oscillation and the frequency of oscillation formulas.
Journal ArticleDOI
First-order filters generalized to the fractional domain
TL;DR: This work shows that low-pass, high- pass, band-pass and all-pass filters can be realized with circuits incorporating a single fractance device and derives expressions for the pole frequencies, the quality factor, the right-phase frequencies, and the half-power frequencies.
