Learning outcomes
|
The aim of the course is to build on the undergraduate courses Linear Electric Circuits and Computer Simulation of Electronic Circuits and to prepare students for the study of system courses and courses devoted to advanced analogue techniques and fast digital circuits. Emphasis is placed on the analysis and design of electronic circuits.
The student will gain the ability to analyze the properties of electronic circuits and design circuits with the required electrical parameters. Emphasis is placed on circuit design.

Prerequisites
|
This course follows Linear Electric Circuits and Computer Simulation of Electronic Circuits courses. The aim of the course (Analysis and Design of Electronic Circuits) is to prepare students for study of advanced analog and digital circuits, and to study the circuits on the boundary between analog and digital area. The emphasis is on analysis and design (synthesis) of electronic circuits.

Assessment methods and criteria
|
Written examination, Home assignment evaluation, Self project defence
Good knowledge of linear electric circuits and computer simulation of electronic circuits is needed. A particular part of the study (besides the lectures and exercises) is the design of a chosen electronic circuit with written report.
