Learning outcomes of the course unit

The nature of the subject will make it possible for students to acquire a practical approach to the design of analog circuits of most diverse types. Having completed the course, students will be able to:
design basic transistor structures with bipolar and unipolar transistors,
explain the internal structure of operational amplifiers and other analog integrated circuits,
design basic linear circuits with operational amplifiers,
design the required transfer function of active filters,
describe the function of non-linear circuits with operational amplifiers,
understand the applications of operational amplifiers in function generators, voltage stabilizers and in A/D and D/A converters.

Prerequisites

Knowledge on the level of the fundamentals of electrical engineering is required, in particular Ohm’s law and Kirchhoff’s laws; students must be able to analyse simple passive circuits, they must know the function of semiconductor diode, the function of bipolar and unipolar transistors.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system.

Assesment methods and criteria linked to learning outcomes

Requirements for the completion of a course are specified by a regulation issued by the lecturer responsible for the course and updated every year.
In each type of exercise, students can obtain up to 10 points, i.e. a total of up to 30 points for exercises. The examination proper is a written examination and students can obtain up to 70 points. The examination is focused on the students’ ability to orient themselves in the design of basic analog circuits and to analyse more complex analog structures.
