Design of stabilized dual power supply
Svoboda, Tomáš ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This bachelor’s thesis is focused on design and construction of stabilized dual power supply with adjustable output voltage in range 0 – 30 V and adjustable current limit in range 0 – 3 A. Power supply consists of line transformer, switching regulator and subsequent application of linear regulator for better output properties. Measurement of output voltage and current is realized by microcontroller ATmega644, which has optical separated inputs. In this thesis the device is designed and simulated. The design is verified by prototype device and then full construction is done. Construction is tested by measurements, which confirm a proper design.

System for precise dynamic measurement of bridge sensors
Čech, Jonáš ; Kolka, Zdeněk (referee) ; Kubíček, Michal (advisor)
This master’s thesis deals with design of measurement system for dynamic measurement of bridge sensors. After a short theoretical part, the own concept is introduced. System can provide sampling rate up to 250 kSa/s with 24-bit resolution. The maximum number of samples is about one and a half milion. At first, the design of analog part was made, in this phase of design the digital part is based on evaluation board with ARM Cortex-M7 and external memory. After final choice of appropriate ICs, the analog and digital part will be integrated into one PCB.

FPGA core for data displaying on computer monitor using VGA port
Pišl, Adam ; Kováč, Michal (referee) ; Kubíček, Michal (advisor)
The aim of this project is to perform the study of a driver for controlling computer monitor using VGA port. The driver is based on FPGA which is used to generate VGA signals. The main purpose of the project is to design a hardware core for gate array which can be used as part of some complex FPGA design to provide a comfortable user interface. The project describes the main part of the VGA driver – module for generating control signals and module for displaying text information that is sent from a PC via serial port interface.

On-board computer for older car
Knápek, Mojmír ; Kubíček, Michal (referee) ; Pospíšil, Martin (advisor)
A thesis is about designing a device, which can add to older car some functions, which are now common like central locking, car-alarm, immobiliser and automatic turning lights on. There will be also solved sensors of input signals, their connecting to the microcontroller and ways to show outputs. In the end of thesis will be designed schematic and board.

Wideband 6GHz RF Signal Generator
Mička, Josef ; Kubíček, Michal (referee) ; Urbanec, Tomáš (advisor)
The goal of this thesis is a design of a wideband high frequency generator with an adjustable output amplitude. The generator is based on a frequency synthesizer ADF4355. The power level of an output signal is adjustable by an attenuator HMC1119. The created generator is accesisible trough an user-friendly control panel or by SCPI commands. Frequency synthesis can run in an integer mode or a fractional mode. The output signal has a very low phase noise when it is running in the integer mode.

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.
