Communication between FPGA and computer - USB high speed
Kollár, Tomáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This bachelors thesis is about a possible interconnection method of FPGA (Field-Programmable Gate Array) chips with the PC through the USB 2.0 bus. These programmable arrays are very important nowadays mainly because of their high speed and high flexibility. Such properties make possible to use FPGAs in applications that require small data bandwidth and also which can utilize the whole bandwidth offered by the USB 2.0 bus. This thesis deals with possibility to use such transfer rate and its short description followed by the design of PCB layout. As the communication between the FPGA and the PC is made possible with the help of a microcontroller capable of handling such requests, I decided to include a short description of its functionality and working principle description in the thesis. The last part describes the communication through the GPIF interface for high-speed transfers.

RS-232 Serial Data Transmitter
Paul, Martin ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The aim of my bachelor thesis is to create an RS-232 transmitter in the Xilinx ISE WebPACK development system with the possibility to set the details of transmitted data by input signals. It is necessary to explore demands of the designed transmitter in terms of consumption of the structural components in the PLD network. The function test of the project was done by the help of development kit.

Analysis of switched-mode LED drivers
Stehlík, Ota ; Vyskočil, Pavel (referee) ; Kubíček, Michal (advisor)
The aim of this thesis is to design, produce and verify the operation of two different LED drivers for automotive industry, which controls the ultra-bright white LEDs. At the beginning of a brief introduction explaining the principle of operation of LEDs. Furthermore theory describes the functions of all three basic drivers involved as buck, boost and buck-boost. Based on the requirements are selected ICs suitable for this implementation, theoretically described their block diagrams including the individual diagrams and eventually these samples are made, revived and measured their parameters.

Small rotor dynamic balancer
Staněk, Michal ; Vyskočil, Pavel (referee) ; Kubíček, Michal (advisor)
Balancing of rotors is used to remove unwanted vibrations caused by uneven distribution of mass around the axis of rotation of the rotor. Operation of an unbalanced rotor may causes shortening of bearing life, fatigue of materials and deformation of shafts. This work deals with construction of a balancing machine (balancer). Because of its good properties, a soft bearing type balancer was chosen for construction. This type of balancer achieves higher sensitivity at the cost of calibration required for each type of rotor. To capture the magnitude of vibration electrodynamics sensors were chosen. To enter data and display results a microprocessor is used.

Fast Beam Current Change Monitor for the LHC
Král, Jan ; Kovalsky, Jan (referee) ; Kubíček, Michal (advisor)
Striktní nároky na systémy ochrany a zabezpečení LHC vyžadují vylepšené metody detekce rychlých ztrát částicového svazku. Rychlý proudový transformátor (FBCT) je měřicí přístroj poskytující informaci o intenzitě shluků urychlovaných částic. Tato diplomová práce popisuje vývoj nového systému ochrany LHC založeného na měření signálu FBCT. Tento systém, monitor rychlých proudových změn částicového svazku (FBCCM), měří signál FBCT v úzkém frekvenčním pásmu a počítá časovou derivaci okamžité amplitudy tohoto signálu. Tato derivace je přímo úměrná ztrátám částicového svazku. Pokud ztráty svazku překročí určitou úroveň, FBCCM přikáže kontrolním systémům zničit svazek kvůli bezpečnosti LHC. Ochrana LHC bude zabezpečena čtyřmi FBCCM, které budou instalovány do LHC v červenci 2014. Bylo zkonstruováno a testováno šest FBCCM. Jejich měřené charakteristiky vyhovují stanoveným požadavkům. FBCCM bylo vyzkoušeno laboratorní simulací reálného prostření LHC.

Multichannel HD-SDI digital video signal converter
Kučera, Stanislav ; Bobula, Marek (referee) ; Kubíček, Michal (advisor)
This master’s thesis deals with the design of six channel SD, HD and 3G HD-SDI digital video signal converter to 10-Gigabit Ethernet. In the introductory part, the conception of designed device is formulated. The theoretical background is provided in four chapters, where main standards and design rules related to digital electronics’ design are analyzed. The emphasis is placed on signal integrity at high-speed interconnects. There mostly practical examples, calculations and simulations are utilized. The design part contains thorough description of main subsystems’ design, implementation of FPGA, SDI input channels and 10-Gigabit Ethernet PHY. In the final part, the first tests and measurements of the build prototype are summarized. As an example, the comparison of signal integrity simulation to measurement is provided.

Digitally controlled multi-quadrant power supply
Chytil, Jiří ; Štekl, Petr (referee) ; Kubíček, Michal (advisor)
This thesis deal with design of multi-quadrant power supply in linear and switching mode. In the case of the switching mode energy recuparation is also considered as well as optimalization of change of load response over time. Power supplies are designed as general purpose laboratory and process power supplies. Power supplies are designed so that they can be connected via galvanic insulated USB interface with a PC
