Basic electronics is a compulsory subject for the first year engineering students from all the disciplines. This book is primarily intended to serve as a textbook in accordance with the syllabus of Basic Electronics offered by various universities in India. It also meets the needs of those readers who want to gain a sound understanding of the principles of electronics. This book has been written in a very simple and lucid manner. Every effort has been made to make the treatments simple and comprehensive. Throughout the book, the stress has been given on fundamental concepts through illustrative examples. Neat and clear diagrams have been used for explanation. A large number of self explanatory accurate diagrams and tables have been used to supplement the text. Exercises and problems are also provided. This will help the students to prepare accordingly. This book is also intended as a textbook for the use in Electronics and Communication courses in polytechnics, IETE, AMIE and for various Engineering Electronics examinations. Thus, primarily designated as an undergraduate textbook for students of science and technology, this study will provide balanced coverage of devices, analog and digital circuits, with an emphasis on analog electronics. I have no claim to the original research in preparing this book. Liberal use of the materials available in the work of eminent authors has been made. I have tried to fashion the vast amount of material available from primary and secondary sources into coherent body of description and analysis. Errors might have crept in despite utmost care to avoid them and author shall be grateful if these are reported along with other suggestions for improvement of the book.

    INTRODUCTION TO ELECTRONICS Price 2.99  |  2.99 Rewards Points

    Electronics is that branch of science and technology which makes use of the controlled motion of electrons through different media and vacuum. The ability to control electron flow is usually applied to information handling or device control.

    SEMICONDUCTOR MATERIALS AND PROPERTIES Price 2.99  |  2.99 Rewards Points

    Atoms are made of 3 types of particles electrons, protons and neutrons. These particles have different properties. Electrons are tiny, very light particles that have a negative charge. Protons are much larger and heavier than electrons and have the opposite charge, protons have a positive charge. Neutrons are large and heavy like a protons. However, neutrons have no electrical charge. Each atom is made up of a combinations of these particles.

    When a p-type semiconductor is suitably joined to n-type semiconductor, the contact surface is called pn-junction. Most semiconductor devices contain one or more pn-junction. The pn-junction is of great importance because it is in effect, the control element for semiconductor devices.

    For reason associated with economics of generation and transmission, the electric power available is usually an a.c. supply. The supply voltage varies sinusoidally and has a frequency of 50 Hz. It is used for lighting, heating and electric motors. But, there are many applications (e.g., electronic circuits) where d.c. supply is needed. When such a d.c. supply is required, the main a.c. supply is rectified by using crystal diode.

    ZENER DIODE Price 2.99  |  2.99 Rewards Points

    A properly doped crystal diode which has a sharp breakdown voltage is known as Zener Diode. In many electronic applications, it is desired that the output should remain constant regardless of the variations in the input voltage or load. In order to ensure this, a voltage stabilizing device, called voltage stabilizer is used. Zener Diode is one of the voltage stabilizer.

    BIPOLAR JUNCTION TRANSISTOR Price 2.99  |  2.99 Rewards Points

    The discovery of the first transistor in 1948 by a team of physicists at the Bell Telephone Laboratories sparked an interest in solid-state research that spread rapidly. The transistor, which began as a simple laboratory oddity, was rapidly developed into a semiconductor device of major importance. The transistor demonstrated for the first time in history that amplification in solids was possible. Before the transistor, amplification was achieved only with electron tubes. Transistors now perform numerous electronic tasks with new and improved transistor designs being continually put on the market. In many cases, transistors are more desirable than tubes because they are small, rugged, require no filament power, and operate at low voltages with comparatively high efficiency. The development of a family of transistors has even made possible the miniaturization of electronic circuits.

    TRANSISTOR BIASING Price 2.99  |  2.99 Rewards Points

    The basic function of transistor is to do amplification. The weak signal is given to the base at the transistor and amplified output is obtained in the collector circuit. One important requirement during amplification is that only the magnitude of the signal should increase and there should be no change in signal shape. This increase in magnitude of the signal without any change in shape is known as faithful amplification. In order to achieve this, means are provided to ensure that circuit (i.e., base - emitter junction) of the transistor remains forward biased and output circuit (i.e., collector– base junction) always remains reverse biased during all parts of the signal. This is known transistor biasing.

    TRANSISTOR AS AN AMPLIFIER Price 2.99  |  2.99 Rewards Points

    The process of raising the strength of a weak signal without any change in its shape is called amplification. A device which amplifies the input signal is called the amplifier. Our purpose here will be to discuss single stage transistor amplifier. By a stage we mean a single transistor with its bias and auxiliary equipment.

    FIELD-EFFECT TRANSISTOR Price 2.99  |  2.99 Rewards Points

    The field-effect transistor (FET) is a semiconductor device which relies on an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material, since their operation relies on the electric field (hence the name field effect) generated by the input voltage. The field effect transistor on the other hand is a “unipolar” device that depends only on the conduction of electrons (N-channel) or holes (P-channel).

    OPERATIONAL AMPLIFIER Price 2.99  |  2.99 Rewards Points

    An operational amplifier, which is often called an op-amp, is a directly-coupled high-gain electronic voltage amplifier with a differential input and usually a single-ended output. An op-amp produces an output voltage that is typically millions of times larger than the voltage difference between its input terminals. An operational amplifier can amplify signals having frequency range from 0 Hz to 1 MHz. This means op-amp can be used to amplify d.c. as well as a.c. input signals.

    SWITCHING THEORY AND LOGIC DESIGN Price 2.99  |  2.99 Rewards Points

    The operations of digital computers, communication systems, calculators, watches and many other systems are based on the principles of digital techniques and these systems are referred to as digital systems. Generally, there are two types of signal namely analog signal and digital signal. A continuously varying signal (voltage or current) is called an analog signal. For example, a sinusoidal signal is analog signal. However, a signal (voltage or current) which can have only two discrete values, is called a digital signal. For example, a square wave is a digital signal. An electronic circuit that is designed for two-state operation is called a digital circuit.
