Analog Electronic Circuits

The contents of the course consists of the following chapters:

INTRODUCTION to analog electronic circuits

AMPLIFIER DISTORTIONS: linear and non-linear distortion, TDH, HD, determination of distortions for different amplifying stages

DIFFERENTIAL AMPLIFIER: realizations, DC and ac analysis, common-mode and differential amplification, models, (a)symmetrical output

POWER AMPLIFIERS: realizations of audio amplifiers, input differential stages, voltage amplifying stages, output power stages (power transistors, classes A; AB; B and others), design of a complete power amplifier, practical examples

OPERATIONAL AMPLIFIERS: ideal, semi-real and real model, input offset parameters, noise, internal circuits of selected operational amplifiers, examples of applications (active filters)

COMPARATORS: requirements, simple comparator, comparator with hysteresis, design of simple circuits with comparators, practical examples of applications

OSCILLATORS: design, relaxation, harmonic (phase shift, Colpitts, Hartley), quartz, circuits of simple signal generators, practical examples of usage

In the frame of laboratory practice students gain their practical experiences within 8 tasks, each including the design, realization on a proto-board and testing.

Students upgrade their fundamental knowledge on analog electronic circuits which are based on transistors, operational amplifiers and comparators. We develop skills to design and not only analyse analog circuits.   

The lectures provide a theoretical background on particular subjects together with presentation of selected designs of practical analog circuits. We motivate students for their own designs of simple circuits. Practical work is focused on the design of selected circuits and their practical realization on protoboard.
