Systematic design of pseudo-differential frequency filters
Milota, Martin ; Langhammer, Lukáš (oponent) ; Sládok, Ondřej (vedoucí práce)
This bachelor thesis deals with the design and analysis of a pseudo-differential filters of higher order. This designed filters work in voltage mode and it is a second-order low-pass filter and a second-order band-stop filter. The filters use three current conveyors and four passive elements. The two lower-pass filters are cascaded together in different ways to form a fourth-order low-pass filter. The functionality of all filters is verified by simulations and low-pass filter as well as experimental measurements. Filter analysis examines the module, phase, common-mode rejection ratio, and behavior of filters while reducing optimal voltage. The results of simulations and experimental measurements are presented using the plots. The conclusion of the thesis is a successful verification functionality of the designed structure and comparison of different ways of connecting the filters to the cascade.

Pseudo-Differential Frequency Filter Using Conveyors
Milota, Martin
The author of this article deals with the design and analysis of a pseudo-differential filter. This designed filter works in voltage mode and is a second-order low pass filter. The filter uses three current conveyors and four passive elements. The proposed circuit reaches the theoretical values in simulations. The simulation results are displayed by modular and phase characteristics.
