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.
