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.
