Preface
This seventh edition ofElectronic Devices hasbeen carefully revised and some important new
topics have been added. Several recommendations from reviewers and current users havebeen
incorporated to make this edition better. A comprehensive coverage of electronic devices and
circuits, including troubleshooting and System Applications, isprovided. Chapters 1through
11areessentially devoted tofundamental discrete devices andcircuits. Chapters 12through 18
primarily coverlinearintegrated circuits. Chapter 19isanewchapter thatiscompletely devoted
toprogrammable analog devices. Data sheets areintroduced incertain areas toprovide aprac-
tical connection with actual devices. Extensive exercises andproblems using Multisim" circuit
simulation are designed tohelp students verify circuit theory and develop troubleshooting and
measurement skills.Referenced Multisim circuit filesareonthe CD packaged with thisbook.
New in This Edition
New on Programmable Devices Chapter 19 introduces field-
programmable analog arrays (FPAAs) and how toprogram them. Also, switched-capacitor
circuits are described because they are basic to FPAA technology.
Circuit-Action This feature is at the end of most chapters. It checks students' un-
derstanding of how changes in certain parameters affect the behavior of acircuit. Given a
specified change in one parameter, students determine the resulting effect (increase, de-
crease, no change) in another parameter or parameters.
lV/ore of High-intensity LEDs are introduced and anew section
on fiber optics has been added.
New Devices New sections on differential amplifiers and the IGBT (insulated gate bipo-
lar transistor) are now included.
Generai lmprovemen Obsolete devices have been replaced, text descriptions have been
reworded for greater clarity, and graphics have been enhanced in certain areas for better ap-
pearance or improved effectiveness.

Student Resources
Companion Website (www.prenhall.com/floyd) This website offers students a free on-
line study guide that they can check for conceptual understanding of key topics.
Multisim" CD·ROM Packaged with each textbook, this CD includes simulation circuits
inMultisim'" 7for selected examples, troubleshooting sections, and selected problems inthe
text. These circuits were created for use with Multisim software, aschematic capture, simu-
lation, and programmable logic tool used by college and university students in their course
of study of electronics and electrical engineering.
Multisim is widely regarded as an excellent circuit simulation tool for classroom and
laboratory learning. However, no part of your textbook is dependent upon the Multisim
software orprovided files. These files areprovided atnoextra cost to the consumer and are
for use by anyone who chooses to utilize Multisim software.
The circuits for the Examples in your text are already rendered "live" for you by Elec-
tronics Workbench inthe Textbook Edition ofMultisim 7.The Textbook Edition enables you
to do the following with the circuits in the Examples folder:
Manipulate the interactive components and adjust the value of any virtual components.
Run interactive simulation on the active circuits and use any pre-placed virtual
instruments.
Run analyses.
Run/print/save simulation results for the pre-defined viewable circuits.
Create your own circuits up to amaximum of 15components.
All oftheremaining circuits onthe CDrequire that you have access toMultisim 7inyour
school lab (the Lab Edition) or onyour computer (Electronics Workbench Student Suite). If
you do not currently have access to this software and wish to purchase it,please call Pren-
tice Hall Customer Service at 1-800-282-0693 or send afax request to 1-800-835-5327.

tion for classes taught online, self-paced, or in any computer-assisted manner.
Multisim CD-ROM Although the CD-ROM accompanying the textbook isprimarily for
the benefit of the student, solution and fault information is provided on the disk for the in-
structor's use. Refer to the CD-ROM organization diagram, which shows the folder hierar-
chy and file naming convention. Circuits containing faults are password-protected so that
only the instructor can identify the faults. Solution files are available for each student cir-
cuit and are also password-protected and accessible only to the instructor.

study aids.
Section Opener Each section in achapter begins with abrief introduction and section ob-
jectives. An example is shown in Figure P-2.
Section Review Each section in achapter ends with areview consisting of questions that
highlight the main concepts presented inthe section. This feature isalso illustrated inFigure
P-2. The answers to the Section Reviews are atthe end of the chapter.
Worked Examples, Related Problems, and Multisim Exercises Numerous worked exam-
ples throughout each chapter illustrate and clarify basic concepts or specific procedures.
Each example ends with aRelated Problem that reinforces or expands on the example by
requiring the student to work through aproblem similar tothe example. Selected examples
feature aMultisim exercise keyed to a file on the CD-ROM that contains the circuit illus-
trated in the example. A typical example with aRelated Problem and aMultisim exercise
is shown in Figure P-3. Answers to Related Problems are at the end of the chapter.
Troubleshooting Sections Many chapters include atroubleshooting section thatrelates tothe
topics covered inthe chapter and that illustrates troubleshooting procedures and techniques.
SyJtem Application System Applications follow the last section in each chapter (ex-
cept Chapter 1) and are identified by a special photographic logo and colored back-
ground design. A practical application of devices or circuits covered in the chapter is
presented. The student learns how the specific device or circuit is used and in many
cases is asked to compare a schematic to a printed circuit board, develop a test proce-
dure, or troubleshoot specific faults. A typical System Application is shown in Figure
P-4. The System Applications are optional and skipping any of them does not affect
any other coverage.
Although they are not intended or designed for use as alaboratory project, most System
Applications use realistic graphics for printed circuit boards and instruments. Results for
the System Applications are provided in the Instructor's Resource Manual.

Portion ofatypical systemapplication section.
Option 1(two terms) Chapters 1through 11can be covered in the first term. Depending
on individual preferences and program emphasis, selective coverage may be necessary. For
example, you may choose to omit Chapter 11if the topic of thyristors is covered in alater
industrial electronics course. Chapters 12 through 19 can be covered in the second term.
Again, selective coverage may be necessary.
Option 2 (one term) By omitting certain topics and by maintaining arigorous schedule,
this book can be used in one-term courses. For example, acourse covering only discrete de-
vices and circuits would cover Chapters 1through 11with, perhaps, some selectivity.
Similarly, a course requiring only linear integrated circuit coverage would cover
Chapters 12through 19.Another approach isavery selective coverage of discrete devices
and circuits topics followed by a limited coverage of integrated circuits (only op-amps,
for example).
Tothe Student
There is asaying that applies to the study of this textbook as well as many other endeavors
in life. It goes like this-Do one thing at a time, do itvery well, and then move on.
When studying aparticular chapter, study one section until you understand it and only
then move ontothe next one. Read each section and study therelated illustrations carefully,
