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.
A deep insight into circuit simulators and advanced analyses; competence in MicroCap and Eagle; operating skills related to the mounting and soldering of PCB components via SMT and THT; ability to revive simple analog electronic circuits.

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.
