Subject description
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.
The subject is taught in programs
Electrical engineering 1st level
Objectives and competences
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.
Teaching and learning methods
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.
Expected study results
After successful completion of the course, students should be able to:
- explain the origins of nonlinear distortions of transistor based amplifiers and to calculate and measure parameters of distortion
- design circuits such as power amplifiers of different classes, circuits with comparators, oscillators
- analyze and design other dedicated circuits with consideration of realistic parameters of operational amplifiers and comparators
- simulate the designed circuits to check their intended functionalities
- measure characteristics of the realized circuit
