Course detail
FEKT-BPA-DECAcad. year: 2021/2022
The course discusses passive and active components for electronic circuits, describing the principles, properties, and applications of such items and proposing an insight into their fundamental production ranges. The topics analyzed comprise, among other issues, the basic layouts of analog circuits with bi- and unipolar transistors and operational amplifiers; in the given context, the relevant parameters, properties, and target applications are also introduced. The proper choice of suitable components is generally emphasized as a vital part of the operational chain. Further, the lectures and tutorials characterize the designing of electronic circuits from the perspectives of their feeding, minimization of spurious effects, and cooling of individual segments. The principles of circuit structuring are outlined, with a particular focus on the fabrication and mounting of printed circuit boards, devices cooling, and transient voltages suppressing. The practices and laboratories are conceived to teach circuit designing and the choice of applicable components, enabling the students to examine the properties of typical circuits with transistors and operational amplifiers.
