Frequency Filters with Controllable Current Followers
Novotný, Matouš ; Herencsár, Norbert (referee) ; Koton, Jaroslav (advisor)
Submitted work engage in suggestion and realization of frequency-selection filters with usage one or more active devices CMI (Current Mirror and Inverter). The preamble of thesis is applied to theory of frequency-selection filters and possible usage of them. The projected circuit layouts are discussed next to would be possible change some of choice parameters of frequency-selection filter. The part of thesis is numerical suggestion of found solutions, their simulation in suitable program and realization.

Design and implementation of wireless charging for embedded systems
Bednařík, Josef ; Bastl, Michal (referee) ; Krejsa, Jiří (advisor)
This thesis deals with the design and realization of wireless power charging circuit for embedded systems. The research section focuses on the various ways and technologies used in applications of wireless power transfer. The theoretical part also briefly characterizes resonant inductive coupling and critical parameters of the transfer. This is followed by realization of various variants of transfer coils and electromagnetic oscillators. Wireless power charging prototype system is created and used for testing purposes to find optimal configuration of resonator. The hardware unit presented in the final part of the thesis exploits microcontroller and implemented software is extended by foreign object detection algorithm along with method to monitor battery charging state.
