Book Review : Microelectronic Circuits by Sedra and Smith

Book Review

Book Review of “Microelectronic Circuits” by Adel S. Sedra (University of Waterloo), Kenneth C. Smith (University of Toronto) and adapted by Arun N. Chandorkar (IIT Bombay). The Book is published by Oxford University Press. And its International student edition is available in Indian Market.

This Book covers all the general topics of subject Analog Electronics and a few topics of Digital Electronics as well. Overall book has covered Analog Electronics quite broadly and most of the topics have in-depth analysis. Author has tried to touch every aspect of analog electronics with the logic behind it.

PREREQUISITE: A course on Network Analysis. Book on “Fundamentals of Electric Circuits” by Matthew N. O. Sadiku and Charles K. Alexander can be followed for this purpose. Other good books are also available for the same course like: “Engineering Circuit analysis” by Hayt, Kemmerly, and Durbin and many other contexts are given in bibliography of the book.

TIP#: Try making short notes, to build better connectivity between topics of the book. And short Notes make it better to revise previous topics.

Contents Covered in the Book:

  1. Introduction to Electronics
  2. Diodes
  3. Bipolar Junction Transistors(BJTs)
  4. MOS Field Effect Transistors(MOSFETs)
  5. Operational Amplifiers
  6. Single Stage Integrated Circuit Amplifiers
  7. Feedback
  8. Differential and Multistage Amplifiers
  9. Digital CMOS Logic Circuit
  10. Filters and Tuned Amplifiers
  11. Signal Generators and Waveform Shaping Circuits
  12. Output stages and Power Amplifiers
  13. Memory and Advanced Digital Circuits

Appendix A is fully based on VLSI Fabrication Technology, but it only gives an overview of VLSI technology and doesn’t contain much depth. Two ports, network theorem and s-domain analysis is given in brief in Appendix, but still a course in Network Analysis is must to understand.

PRINT QUALITY: Print is quite good for this book. Book is printed on grayscale, not just black and white. Font is small but readable and text is not monotonous, as it develops interest throughout the book. Book is full of graphs, diagrams with good quality print and connecting text.

DETAILING: This book has tried to cover most of the topics of analog electronics, in best way possible. Meanwhile, tried to make text interesting by providing diagram and graph to support.

  • 1st Chapter contains all the basic concepts related to Analog Electronics, with a brief overview of signals part. These topics are going to be used throughout the book.
  • The chapter on diode has various models, which are necessary to build imagination while solving problems in different conditions.
  • BJTs and MOSFETs are individually dealt as devices with their operation in different conditions. Small signal operations and models are covered nicely with graphs and diagrams.
  • Single stage BJT amplifiers as Common Emitter (CE), Common Base (CB) and Common Collector (CC) amplifiers are covered in best way possible. Similarly MOSFET amplifiers as Common Source (CS), Common Gate (CG) and Common Drain (CD) amplifiers are also covered.
  • The MOSFET differential pair and BJT differential pairs both are explained separately.
  • Effect of Internal Capacitances and High frequency model in BJTs and MOSFETs, is also given in this book.
  • Digital Logic Gate circuits with CMOS and CMOS Digital Logic Inverter is also explained in depth (with most of the things being explained through graph).
  • Filters, Tuned Amplifiers are covered as separate unit from Oscillators, to justify each of them and make their circuits distinguishable.

EXAMPLES: The solved examples are supportive to the text and should be done while reading text to get better understanding. Examples are mostly subjective in nature and few examples are also circuit design based. Solved Example of Diodes, BJTs and MOSFETs biasing, and also with small signal concept develop a systematic and nice approach of solving problem. Spice simulation examples are also given at the end of every chapter, which gives the brief idea of how to implement circuits on software platform (If needed, can be studied).

EXERCISES: There are two types of exercises in this book. One is within the chapter text, and follows the concept of solved example just before it. This type of exercises actually checks the concept gained by twisting the problem slightly or changing the data involved.

The other exercises are at the end, and contain mix of concepts and many new problems. This set of Exercises has variety of questions and can be solved to develop strong grip over topic. Exercise questions of Operational amplifier are also good, and needs to be done if text is read from same book. Exercise Question of BJT and MOSFET based amplifiers and differential amplifiers can be done through this book. Student is recommended to solve the exercise problems if he/she is weak in a particular topic.

DRAWBACKS: Few drawbacks of this book are:

  • Operational Amplifier chapter should have included more things and could be connected better with other topics, though a decent level is attainted for this topic.
  • Junction Field Effect Transistors (JFETs) are also not explained in detail, in this book. It is only a subpart of Chapter 4 on MOSFETs.
  • Few questions in exercises are design based and may not be helpful for competitive exams, so need to identify such question to save time.
  • The book doesn’t have objective question and don’t provide faster solving approaches. But student may be able to develop his own methods after going through the book.
  • The book has quite wide spectrum and a student has to always make short notes to develop connectivity with topics. Without short notes a good level of understanding is lost.

OVERALL EXPERIENCE:

This book is a one stop solution for Analog Electronics and covers almost whole syllabus under this subject. Book is quite interactive in nature and explains most of the tough topics quite nicely, using diagrams and graphs. If book is completed with examples and exercises it gives you more than sufficient knowledge, until and unless you want to specialize in a particular field.

Students can also follow video lectures online if text is difficult to them but concept depth is best in this book for analog. For Op-Amps you can use “Op-Amps and Linear Integrated Circuits” by Gayakwad, if need more content. For question solving a student can also go for Kanodia series, only if text is understood properly and needs to do practice for competitive exams.
