Controlling of programmable analogue circuit
Sobotka, Josef ; Hanák, Pavel (referee) ; Vrba, Kamil (advisor)
This work deals with the design of the control software for the programmable analog circuit adjustable by means of a computer via the serial interface for the computer, as well as for programming the microcontroller. In addition, analyses the internal structure of programmable analog circuit on which it is proposed to further control, design of printed circuit boards for final programming and test equipment and measurement of the basic parameters of the circuit (transmission and phase frequency characteristics of parts and units).

Communication assembly for optical cableless linking
Kapuš, Martin ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
This Graduate Thesis is about communication module for optical wireless network. This device read data from RS232 port and two analog inputs and sends it through internet to a remote Computer. Furthermore allows voice communication between local user on module and user on remote computer. Device allows communication with standard headphones and microphone, or with Bluetooth handsfree. Basic part is microprocessor MCF5223 and Bluetooth Ezurio BISM II module. Control program has been written in C language. Printed circuit is created by EAGLE program. This device is managed via web interface and settings have been stored into EEPROM memory. Work contains description of separately parts and blocks, source code of program, description of source code and printed circuit designs.

Optimization of AC signal voltage amplifier
Vaculík, Lukáš ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
The Bachelor thesis deals with the analysis of the voltage amplifier and with simulation of its behavior using program LTspice. The basics for working in this simulation program are also described. The content of thesis is also a measurement of the actual implementation of the amplifier for comparison with the performed simulations. Subsequently, there are outlined possible solutions how to optimize the scheme in order to achieve the best possible results in the monitored parameters, especially the distortion and amplitude of the output signal in the thesis. The scheme was presented by Meatest, s.r.o., where the amplifier is part of a multifunction calibrator. Theoretical part, which serves as an introduction to the issue, describes the components and introduces important concepts, is also included in the thesis.

Signal and data logger
Borsányi, Tamás ; Vyskočil, Pavel (referee) ; Kolouch, Jaromír (advisor)
The goal of this project is to design a signal and data logger, which captures analog and digital signals with very long record time. The device supports multichannel complex triggering, a real-time oscilloscope-like mode and an offline mode for analyzing of previously sampled data. This project contains detailed analysis of the topic, description of hardware and software solutions and used methods. The thesis also contains verification tests and measurements. This device will be mainly used for hardware debugging of microprocessor based applications.

Modernization of the master clock for slave clocks controlling
Pokorný, Jiří ; Číž, Radim (referee) ; Krajsa, Ondřej (advisor)
This diploma thesis describes modernization of the master clock HN 50 created by company ELEKON, s.r.o. Master clock can be used for controlling of analog or digital slave clock or for switching school bells. Exact differences between old and new version of the clock are described and ways of synchronization and controlling of slave clock are explained. Main goal of modernization is applying the SMT technology for automation of production. Another problems and shortcomings of previous version are developed, such as new power supply structure, selection of a new microcontroller and usage of several different displays. Every problem is developed and new solutions are chosen. Last part of the document describes the software which is clarified on several flowcharts. Outputs of the thesis are complete schematics, printed circuit boards and 3D models of the modernized device.

Integrated temperature sensor bipolar core
Fránek, Jakub ; Prokop, Roman (referee) ; Kledrowetz, Vilém (advisor)
Cílem této práce je popsat možné způsoby realizace teplotního senzoru na křemíkovém čipu v běžných CMOS výrobních technologiích a představit konkrétní implementaci analogového jádra teplotního senzoru využívajícího bipolární tranzistory ve výrobní technologii TSMC 110. Techniky jako chopping, dynamic element matching nebo trimování byly použity k navržení obvodů, jejichž simulovaná 3 přesnost měření je ±3.5 °C bez trimování nebo ±0.6 °C s po jedné trimovací operaci napříč vojenským teplotním rozsahem. Navržené obvody zabírají pouze 0.012 mm čtverečních plochy čipu a jejich celkové parametry jsou srovnatelné s výsledky současných publikovaných prací.
