Design of basic analogue building blocks with fractional-order transfer
Theumer, Radek ; Staněk, Miroslav (referee) ; Langhammer, Lukáš (advisor)
This diploma thesis is focused on design of the analogue circuit structures with integer-order and fractional-order transfer. The ways in which fractional-order transfer functions can be achieved are mentioned in the introduction. Two basic building blocks with the ability to control its transfer function order and frequency, such as integrator and differentiator respectively, were designed. A non-traditional active element was used in proposed analogue building blocks. In addition, the inner structure of this active element has been improved to provide the ability to control another suitable parameters. Aplication of the proposed fractional-order integrators is presented by employing into the frequency filter. Simulations are performed with help of transistor-level models of two different technologies: CMOS TSMC 0,18 um in the OrCAD Pspice software and I3T25 in the CADENCE Virtuoso software too. All proposed circuit structures are realized on the printed circuit board (PCB) and then measured experimentally. The last part is focused on comparative measurements of the filters with fractional-order integrator proposed by another author.

Filtering structures containing a fractional-order elements
Kubát, Pavel ; Kubánek, David (referee) ; Dvořák, Jan (advisor)
Bachelor work deals with fractal order frequency filters. The first part describes basic division frequency filters, the following part describes fractional order frequency filters and design of the circuit with fractal order. The following part contains active elements that are used for the design of the frequency filters. The last theoretical part shows design method for frequency filters, where signal flow graph is shown. Realisation, simulation and measurement are described in the practital parts.
