From the Inside Flap:

When the first edition of this book was published it represented a very novel approach to the teaching of electronics. Up to that time most texts in this area had adopted a decidedly 'bottom-up' approach to the subject. They often started by looking at semiconductor materials and worked their way through diodes, transistors and biasing, before looking at simple amplifier circuits. Eventually, several chapters later, they might actually look at the uses of the circuits being considered.

The first edition of Electronics: A Systems Approach pioneered a new approach to the teaching of electronics by explaining the uses and required characteristics of circuits before embarking on detailed analysis. This aids comprehension and makes the process of learning much more interesting. Another innovation within the first edition was that it provided a unified treatment of both analogue and digital electronics within a single volume, allowing common ground between these two areas to be developed. While many texts are still resolutely device centred, it is pleasing to see that several more enlightened authors are now following a more systems oriented approach.

One of the great misconceptions concerning this approach is that it is in some way less rigorous in its treatment of the subject. It seems that some instructors believe that any book that does not start with several pages of complex mathematics does not do justice to the teaching tradition. The systems approach does not define the depth to which a subject is studied but only the order and manner in which the material is presented. Many students will need to look in detail at the operation of electronic components and to understand the physics of its materials; however, this material will be more easily absorbed if the characteristics and uses of the components are understood first.

One of the many advantages of a systems approach is that it allows a single text to be used by a wide variety of students. All engineers and scientists should have an appreciation of the basics of electronics since it is an essential enabling technology across a broad spectrum of disciplines. Presenting the information in a 'top-down' manner makes it easier to assimilate for all readers. For the student who is destined to be an electronic specialist this route provides the information in the most accessible order, thus aiding comprehension. For the non-specialist the information is presented such that the reader may progress as far through the text, or through the various sections, as is appropriate to give the required level of detail. The text includes the circuit analysis and design techniques needed by students destined for more advanced circuit design courses. However, it is presented after a more general introduction to the topic such that non-specialists may easily skip the detail without harming their understanding of the basics.

Throughout the text parallels between analogue and digital techniques are highlighted and a systems approach to design is encouraged. Numerous examples are given to illustrate the techniques being discussed and design case studies are included at the end of each chapter to reinforce the material and to promote a systematic approach.

Who should read this book
This text is intended for undergraduate students in all fields of engineering and science. For students of electronics and related disciplines it provides a coherent set of material suitable for first level courses in analogue and digital design. For other students it includes most of the electronics material that will be required throughout their course.

New material within this edition
This second edition has given an opportunity to update the text and to take account of developments in a very rapidly changing field. It has also permitted several major revisions of the text. The major changes to the book are:

    *    The text now includes a large number of computer simulation exercises as an aid to comprehension. The exercises make use of a set of demonstration files that may be downloaded free of charge over the Internet and a software simulation package that can be obtained free of charge from its supplier.

    *    A short section on laboratory instruments has been included which describes the operation of oscilloscopes and digital multimeters.

    *    A new section has been added on electromagnetic compatibility (EMC) to reflect the growing recognition of the importance of this topic to all engineers.

    *    A substantial new section has been added on programmable logic devices (PLDs) to replace the limited treatment of array logic in the first edition.

    *    The number of worked examples within the text has been increased.

    *    Additional self assessment exercises have been added to those at the end of the chapters.

    *    A new appendix describes the IEC 617 symbols for logic elements.

    *    An appendix now gives numerical answers to many of the end of chapter exercises. If the number of the exercise is set in italic type, for example, see Exercise 1.11, on page 14, this indicates that the answer can be found in this appendix.

Circuit simulation
Throughout the book there are numerous Computer simulation exercises that support the material in the text. These are marked by a computer icon in the margin as shown on the left. The exercises may be performed using any suitable circuit simulation package, although the use of PSpice is recommended. The PSpice simulation package is produced and marketed by the MicroSim Corporation and is one of the most widely used packages both within industry and within Universities and Colleges. PSpice is based on the industry standard SPICE simulation package and comes with a suite of programmes allowing the schematic capture of circuits and the graphical display of simulation results.

MicroSim produce a free evaluation version of the software which incorporates most of the important features of the package but is restricted in the complexity of the circuits that may be simulated. This evaluation version is completely adequate for the needs of this text. Readers with their own computer may obtain a free copy of the software by contacting MicroSim at their website on the Internet.

Their URL is: microsim

After completing an on-line application form the free software will be dispatched by post within a few days. Those making use of a computer within a University or College should check with the system manager to see if PSpice is already available. If not, they should request that it be loaded.

Since the main purpose of this text is to teach electronics rather than simulation, the text does not attempt to teach the use of PSpice or any other simulation package. Most electronics programmes now include a course on computer simulation that looks at the modelling methods used and considers the limitations and restrictions of these tools. Such courses are not normally taken by non-electronics students. I believe that all students can benefit from the use of simulation when studying electronics since it gives a very graphic insight into the operation and characteristics of circuits. Fortunately, the skills required to perform simple simulations can be learnt in a few minutes and I would suggest that all readers of this text should take advantage of these powerful packages. Indeed, it may be beneficial for electronics students to gain an insight into the use of simulation by using it at a basic level with this text before taking a more detailed simulation course.

One of the barriers to the use of simulation in the study of electronics is the time taken to prepare the circuit files required by the simulator. Even though packages such as PSpice permit circuits to be entered in a straightforward way through the use of a schematics capture package, it can take several minutes for even a simple circuit to be entered (particularly for the inexperienced). In order to speed up the use of simulation, and to encourage readers to make maximum use of these powerful tools, a suite of demonstration files is available to complement this book. The presence of the demonstration files means that it is possible to simulate the various circuits without a detailed knowledge of the simulation package being used. All that is required is the ability to load a file, run the simulation and make minor modifications to the circuit. Such skills could be gained from a short demonstration within a laboratory session, or could be obtained in a few minutes by referring to one of the many excellent texts available on this topic (those using PSpice can find a list of books on this package on the MicroSim website).

Each demonstration file is provided in two formats: firstly as a net list and secondly as a PSpice schematics file. The first of these formats is

From the Back Cover:

Electronics play a central role in our everyday lives, being at the heart of much of today’s essential technology – from mobile phones to computers, from cars to power stations. As such, all engineers, scientists and technologists need a basic understanding of this area, whilst many will require a far greater knowledge of the subject.

 

The third edition of Electronics: A Systems Approach is an outstanding introduction to this fast-moving, important field. Fully updated, it covers the latest changes and developments in the world of electronics. It continues to use Neil Storey’s well-respected systems approach, firstly explaining the overall concepts to build students' confidence and understanding, before looking at the more detailed analysis that follows. This allows the student to contextualise what the system is designed to achieve, before tackling the intricacies of the individual components. The book also offers an integrated treatment of analogue and digital electronics highlighting and exploring the common ground between the two fields.

 

Throughout the book learning is reinforced by chapter objectives, end of chapter summaries, worked examples and exercises. This third edition is a significant update to the previous material, and includes:

 

  • New chapters on Operational Amplifiers, Power Electronics, Implementing Digital Systems, and Positive Feedback, Oscillators and Stability .
  • A new appendix providing a useful source of Standard Op-amp Circuits
  • New material on CMOS, BiFET and BiMOS Op-amps
  • New treatment of Single-Chip Microcomputers
  • A greatly increased number of worked examples within the text
  • Additional Self-Assessment questions at the end of each chapter

 

Dr. Neil Storey is a member of the School of Engineering at the University of Warwick, where he has many years of experience in teaching electronics to a wide-range of undergraduate, postgraduate and professional engineers. He is also the author of Safety-Critical Computer Systems and Electrical and Electronic Systems both published by Pearson Education.
