A device for demonstrating the function of oscillators with fractional-order elements
Walach, Vít ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This bacherol thesis deals with fractional-order elements and it’s application for RC oscillators. The aim is to carry out simulations of two different oscillators using fractional-order capacitors and then design and manufacture a device demonstrating the function of the selected oscillator. Several methods of approximation of constant phase elements are described in this work, including their circuit realization for Foster and Cauer structures. The selected RC oscillators are modeled numerically in Matlab, as well as simulated in Pspice, so that the results of both simulations can be compared. The presented oscillator with two constant phase elements is implemented on a printed circuit board. At the end of the work, the results of experimental measurements are presented in comparison with simulations.
