Band Gap - accurate voltage reference
Bubla, Jiří ; Petržela, Jiří (referee) ; Kolka, Zdeněk (advisor)
This diploma thesis is specialized on a design of a high accuracy voltage reference Bandgap. A very low temperature coefficient and output voltage approx. 1,205V are the main features of this circuit. The paper contains a derivation of the Bandgap principle, examples of realizations of the circuits and methods of compensation temperature dependence and manufacture process, design of Brokaw and Gilbert reference, design of a testchip and measurement results.

Representation of a healthy lifestyle and the ideal of beauty in the media: comparison of lifestyle magazines
Bubla, Jiří ; Jirák, Jan (advisor) ; Vochocová, Lenka (referee)
The thesis "Representation of a healthy lifestyle and the ideal of beauty in the media: comparison of lifestyle magazines" deals with the representation and media image of a healthy lifestyle and the ideal of beauty in four Czech printed lifestyle magazines Muscle & Fitness, Dieta, Blesk zdraví and Nová Regena in period from May to October 2013. This thesis aims to analyze presented titles and find out how these magazines represent individual and different way of healthy lifestyle and the ideal of beauty. Under this objective, the content of the thesis is divided into a theoretical part, Czech media system, methodology part and analytical - empirical part. The theoretical part discusses the social and media construction of reality as an anchor basis, follows the theory of media representation, its components narratives and seriality and the theory of stereotyping. It is also analyzed the theoretical framework of lifestyle and the phenomena of contemporary society. The representation of a healthy lifestyle and the ideal of beauty was in examined magazines analyzed by a combination of quantitative and qualitative methods of content analysis, whereby the emphasis was on linking theory and research. Quantitative analysis served as a supporting factor primarily for detecting the basic frequency of...
