Entry knowledge

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.

Rules for evaluation and completion of the course



Laboratory lessons and computer exercises are obligatory. Justified absence from laboratory lessons or computer exercises can be made up after prior arrangement with the instructor, usually in the credit week.

Aims

To obtain basic knowledge of applying analog technology in the broadest sense, i.e. from simple building blocks with diodes, bipolar and unipolar transistors up to the application of integrated analog circuits in concrete applications
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.
