Preface to Microelectronic Circuits PDF

Microelectronic Circuits, Seventh Edition, is intended as a text for the core courses in electronic circuits taught to majors in electrical and computer engineering. It should also prove useful to engineers and other professionals wishing to update their knowledge through self-study.

As was the case with the first six editions, the objective of this book is to develop in the reader the ability to analyze and design electronic circuits, both analog and digital, discrete and integrated. While the application of integrated circuits is covered, the emphasis is placed on transistor circuit design.

This is done because of our belief that even if the majority of those studying this book were not to pursue a career in IC design, knowledge of what is inside the IC package would enable the intelligent and innovative application of such chips.

Furthermore, with the advances in VLSI technology and design methodology, IC design itself has become accessible to an increasing number of engineers.


It has been our philosophy that circuit design is best taught by pointing out the various tradeoffs available in selecting a circuit configuration and in selecting component values for a given configuration. The emphasis on design has been retained in this edition.

In addition to design examples, and design-oriented exercises and end-of-chapter problems (indicated with a D), the book includes on its website an extensive appendix (Appendix B) where a large number of simulation and design examples are presented.

These emphasize the use of SPICE, the most valuable circuit-design aid.

New to Microelectronic Circuits 7th Edition

While maintaining the philosophy and pedagogical approach of the first six editions, several changes have been made to both organization and coverage.

Our goal in making structural changes has been to increase modularity and thus flexibility for the instructor, without causing disturbance to courses currently using the sixth edition.

Changes in coverage are necessitated by the continuing advances in technology which make some topics of greater relevance and others of less interest.

As well, advances in IC process technology require that the numbers used in the examples, exercises and end-of-chapter problems be updated to reflect the parameters of newer generations of IC technologies (e.g., some problems utilize the parameters of the 65-nm CMOS process).

This ensures that students are acquiring a real-world perspective on technology. To improve the presentation, a number of chapters and sections have been rewritten for greater clarity. Specific, noteworthy changes are:

1. New End-of-Chapter Problems and a New Instructor’s Solutions Manual. The number of end-of-chapter problems has increased by about 50. Of the resulting 1532 problems, 176 are entirely new and 790 have new data. The new Instructor’s Solutions Manual is written by Adel Sedra.

2. Expand-Your-Perspective Notes. This is a new feature providing historical and application perspectives. About two such notes are included in each chapter. Most are focused on notable circuit engineers and key inventions.

3. Greater Flexibility in Presenting the MOSFET and the BJT. Two short and completely parallel chapters present the MOSFET (Chapter 5) and the BJT (Chapter 6).

Here the focus is on the device structure and its physical operation, its current-voltage characteristics, and its application in dc circuits. The order of coverage of these two chapters is entirely at the instructor’s discretion as they have been written to be completely independent of each other.

4. A Unified Treatment of Transistor Amplifiers. The heart of the first course in electronics is the study of transistor amplifiers.

The seventh edition provides a new approach to this subject: A new Chapter 7 begins with the basic principles that underlie the operation of a transistor of either type as an amplifier and presents such concepts as small-signal operation and modeling.

This is followed by the classical configurations of transistor amplifiers, biasing methods, and practical discrete-circuit amplifiers.

The combined presentation emphasizes the unity of the basic principles while allowing for separate treatment of the two device types where this is warranted. Very importantly, we are able to compare the two devices and to draw conclusions about their unique areas of application.

5. Improved Presentation of Cascading. Chapter 8 dealing with the basic building blocks of IC amplifiers has been rewritten to improve presentation. Specifically, the development of cascading and the key circuit building blocks, the cascade amplifier and the cascade current source, is now much clearer.

6. Clearer and Simplified Study of Feedback. The feedback chapter has been rewritten to improve, simplify and clarify the presentation of this key subject.

7. Streamlined Presentation of Frequency Response. While keeping the treatment of frequency response altogether, the chapter has been rewritten to streamline its flow and simplify and clarify the presentation.

8. Updated Treatment of Output Stages and Power Amplifiers. Here, we have updated the material on MOS power transistors and added a new section on the increasingly important class-D switching power amplifier.

9. A More Contemporary Approach to Operational Amplifier Circuits. While maintaining coverage of some of the enduring features and subcircuits of the classical 741 op-amps, its total coverage is somewhat reduced to make room for modern IC op-amp design techniques.

10. Better Organized and Modernized Coverage of Digital IC Design. Significant improvements have been made to the brief but comprehensive coverage of digital IC design in Part III.

These include a better-motivated study of CMOS logic circuits (Chapter 14) which now begins with logic gate circuits. The material on logic circuit technologies and design methodologies as well as the advanced topic of technology scaling and its implications have been moved to Chapter 15.

This modularly structured chapter now deals with a selection of advanced and somewhat specialized topics. Since bipolar is hardly ever used in new digital design, coverage of ECL has been significantly reduced. Similarly, BiCMOS has become somewhat of a specialty topic and its coverage has been correspondingly reduced. Nevertheless, the complete material on both ECL and BiCMOS is now available on the book’s website. Finally, we have added a new section on image sensors to Chapter 16 (Memory Circuits).

11. Increased Emphasis on Integrated-Circuit Filters and Oscillators. A section on a popular approach to integrated-circuit filter design, namely, Transconductance-C filters, has been added to Chapter 17.

To make room for this new material, the subsection on stagger-tuned amplifiers has been removed and placed in Appendix H, on the website. The cross-coupled LC oscillator, popular in IC design, has been added to Chapter 18.

The section on precision diode circuits has been removed but is still made available on the website.

12. A Useful and Insightful Comparison of the MOSFET and the BJT. This is now included in Appendix G, available on the website.
