Harness tester
Smola, Tomáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This thesis deals with issue and construction of wire harness tester. In the first place, is this thesis focused on market exploration and comparison of comercial testers with concrete requirements for small batch production. I will try to find a suitable product in worldwide market, which would be convenient for company producing construction machinery. For testing switchboard harness we need to test interconnections between connectors, resistors, relays, diodes, transils and switches in the dashboard. If I can not find some product, I will try to design some new tester. My priorities will be testing all components in harness, maximum flexibility of tester for the future trends in contruction of rollers and user friendly control.

Design and realisation of the five-levels quantizator
Zeman, Pavel ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
The work deals with design and realisation of the five-levels high-speed quantizer using switched-current technique (SI). The main aim is to use an advantage of switched-current technique like potential of the high-speed operation and to minimize disadvantages at all. Flash structure of the quantizer is used to ensure high-speed operation. It is supposed that the quantizer will be part of greater integrated systems such as higher-order delta-sigma modulators. Simulations are performed in CADENCE simulation tool using AMIS CMOS 0,7 µm technologic process.

Multimedial education interface for programming and debugging software for AVR microcontrollers
Šrajla, Josef ; Sajdl, Ondřej (referee) ; Pavlík, Michal (advisor)
Diploma thesis is concerned with programming of AVR microprocessors. Main task was development of compact environment where user can learn methods necessary for successful programming of microprocessor. It was necessary to make an application enabling interactive simulation of processor to reach this goal. User-friendly control, simplicity and low hardware demands are main advantages of this application. Only computer with internet connection is demanded. Complicated installation, usual for similar products, is avoided.

Motor test platform monitoring system
Klecker, Jan ; Musil, Vladislav (referee) ; Pavlík, Michal (advisor)
The content of this thesis is to design system for temperature measurement of critical parts of NXP electric engine testbench. In the theoretical part will be analysed temperature measurement by temperature sensors and its connecting to microcontroller. The practical part is focused on realization of device for temperature measurement. This device will be based on NXP microcontroller from Kinetis MKVxx family.

Satellite power supply
Pavlík, Arnošt ; Boušek, Jaroslav (referee) ; Pavlík, Michal (advisor)
The bachelor thesis consists of the design and realization switched source for use in satellites of Cubesat type. The paper describes the theoretical knowledge of switched sources. The document also contains basic theoretical knowledge for the application of electronic devices in the cosmic environment and contains a description of the Cubesat concept and their application benefits. In the paper there is systematically described how to design a power source for application in a Cubesat satellite.

Linear active filter of supply voltage „Ripple Blocker“
Vlček, Pavel ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This work deals with a methods for increasing the PSRR of the linear active filters of supply voltage or if linear regulators and voltage range of supply, primarily his minimal value. In the work are used ideal parts of reference voltage source and reference current source. The work describes how to eliminate effect of feedback loop on the PSRR, how to decrrease minimal power supply voltage and how to set stability of total schematic.

Switching LED drivers
Doležal, Miroslav ; Pavlík, Michal (referee) ; Šteffan, Pavel (advisor)
In this bachelor’s these are three basic typologies of drivers (step down, step up, step up and down output voltage) described. Five specific integrated circuits fulfilling the requirement for supplying LED diodes are selected. The output of this thesis is the design and construction of LED driver for supplying high brightness LEDs with 900 mA constant current.
