Control of graphic OLED display with Atmel microcontroller
Bartošík, Vladislav ; Lattenberg, Ivo (referee) ; Hanák, Pavel (advisor)
This Master's thesis deals with design and a realisation of a device controlling an OLED display, Densitron DD-25664-1A. This display has a resolution of 256 x 64 pixels and allows displaying of 4-bit grayscale. The proposed utility software implements the initialization and termination functions, two sets of fonts { Latin and Greek letters and functions for rendering graphics and text. The result of the project is a device with the controlling software.

Nano-ammeter with galvanic isolation
Šimka, Marek ; Kubíček, Michal (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with all the aspects, that are important in the designing of the nano-ammeter. In theoretical part, there are described possible ways to measure electrical current of very low values. Other parts of the thesis describe all parameters, which are influencing measurement accuracy. These are, for example, unwanted and leakage currents, but also other parasitic phenomena that may occur. Thesis explains how to minimize unwanted currents and other influences. Practical section provides more detailed description of the proposed main scheme. There are also described components, that have been selected as the main parts of the nano-ammeter circuit. Subsequent part contains analysis of printed circuit board including all layers. Furthermore, the thesis deals with the realization of equipment and possible errors. The results of the bachelor are summarized in the last chapter.

System level analysis of thermal properties of integrated circuits
Vaněk, Martin ; Jirák, Josef (referee) ; Frk, Martin (advisor)
Hlavním cílem této práce je shrnout základní poznatky o tématech spojených s teplem, se zaměřením na aplikace v elektrotechnice, a provést měření tepelného odporu pouzder integrovaných obvodů. První část je praktická a zabývá se teorií přenosu tepla, tepelnými vlastnostmi materiálů a metodologií JEDEC pro měření tepelných vlastností pouzder integrovaných obvodů. Druhá část se skládá ze sestrojení teplotní komory s přirozeným prouděním, návrhu testovacích desek plošných spojů a tepelných měření. Na závěr je shrnuta metodologie pro měření tepelného odporu čip-okolí spolu s uvedením praktických poznatků z předchozích měření. Tato práce může sloužit jako základ pro další vyhodnocování tepelných vlastností integrovaných obvodů a pro ověřování přesnosti tepelných simulací. Také může pomoci při vyhodnocování tepelné vodivosti desek plošných spojů.
