Design of Electronic Circuits

FEKT-BPC-NEOAcad. year: 2022/2023

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 tutorials 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.

Learning outcomes of the course unit

The classes will acquaint the students with the fundamental range of passive and active components for analog electronic circuits, thus enabling them to reliably use catalog data in selecting suitable components for a given application and to recognize the functional principles related to various circuit elements. Upon completing the course, the students will be able to practice the typical circuit layouts comprising bipolar/unipolar transistors and operational amplifiers; design simple analog electronic circuits, including their power supply units; employ a simulator to verify the properties of the designed circuit and, if necessary, to optimize the parameters needed; seek and eliminate problems in the actual design of circuits and printed circuit boards; and to outline applicable solutions for signal and supply wiring, together with a convenient approach to conduct away the heat generated by power components.

Prerequisites

Good knowledge of the topics discussed within Electrical Engineering 1 and 2 is required, and a basic precursory insight into the physics of semiconductors may help the students substantially to reach successful completion of the course.
