Abstract
Electronic components are the basic building blocks of electronic circuits, essential for controlling
and manipulating electrical signals. Key components include resistors, which regulate current flow;
capacitors, which store and release energy; diodes, which allow current to flow in one direction; transistors,
used for amplification and switching; and inductors, which store energy in a magnetic field. These
components work together in circuits to perform specific functions, such as signal processing, power
management, and data transmission, forming the foundation of modern electronic devices like smartphones
and computers.
This document is a course support for electronic components intended for students in the Master 2 in
Physics of Materials, who wish to deepen their knowledge in the subject. This document aims particularly to
support the personal work of the student and to make the professor's work more effective. The aim behind
this course is to simplify the essential ideas contained in this course and to make them didactically simpler.
Consequently, the emphasis will be placed on physical explanations, demonstrations, and examples when
they are essential for the students' good understanding. In the context of this course, we are mainly interested
in presenting the content of the subject of electronic components in accordance with the official program.
The program is structured in the form of four chapters; these chapters allow the main concepts of electronic
components to be introduced in a simple way.
The first chapter, entitled Diodes, is devoted to presenting basic notions on semiconductors as an
introduction and more mainly to the in-depth study of PN junction diodes, their polarization, their modeling
and their different functions.
The second chapter, entitled Transistors, will be dedicated to the study of the different types of junction
and field effect transistors, their operating principle, their characteristics and their polarization in static
and dynamic regime.
The third chapter, entitled Transistor Amplifiers ; is devoted to examining their operation, their
equivalent diagrams, their main electrical characteristics and their applications in modern technology.
The last chapter deals with the different types of feedback in positive or negative amplifiers and their
general properties. the study of their influence on gain fluctuations and input and output impedances in
electrical circuits.
A large number of bibliographic references have been used to develop this document. Each chapter is
preceded by the main part of a course followed by assessment questions with their indicators. I hope that
this handout will serve as a valuable working tool for level License and Master in physics and electronics
students.
