Electronics Devices and Circuit Theory
( Robert L. Boylestad, Louis Nashelsky )
This book can be used as a reference book for the Electronics Engineering in
the second semester of Engineering in Tribhuvan University. It can also be
referred for Pokhara University, Kathmandu University and Purbanchal
University. All departments (Civil, Computer, Mechanical, Electronics,
Electrical, etc. refers to this book for their second semester Electronics
Engineering subject.
BACKGROUND
The preparation of the preface for the 11th edition resulted in a bit
of reflection on the 40 years since the first edition was published in 1972
by two young educators eager to test their ability to improve on the
available literature on electronic devices. Although one may prefer the term
semiconductor devices rather than electronic devices, the first edition was
almost exclusively a survey of vacuum-tube device a subject without a single
section in the new Table of Contents. The change from tubes to predominantly
semiconductor devices took almost five editions, but today it is simply
referenced in some sections. It is interesting, however, that when
field-effect transistor (FET) devices surfaced in earnest, a number of the
analysis techniques used for tubes could be applied because of the
similarities in the ac equivalent models of each device.
We are often asked about the revision process and how the content of a new
edition is defined. In some cases, it is quite obvious that the computer
software has been updated, and the changes in application of the packages
must be spelled out in detail. This text was the first to emphasize the use
of computer software packages and provided a level of detail unavailable in
other texts. With each new version of a software package, we have found that
the supporting literature may still be in production, or the manuals lack
the detail for new users of these packages. Sufficient detail in this text
ensures that a student can apply each of the software packages covered
without additional instructional material
