The subject matter of electronics may be divided into two broad categories: the application of physical
properties of materials in the development of electronic control devices and the utilization of electronic
control devices in circuit applications. The emphasis in this book is on the latter category, beginning
with the terminal characteristics of electronic control devices. Other topics are dealt with only as
necessary to an understanding of these terminal characteristics.
This book is designed to supplement the text for a first course in electronic circuits for engineers. It
will also serve as a refresher for those who have previously taken a course in electronic circuits.
Engineering students enrolled in a nonmajors’ survey course on electronic circuits will find that portions
of Chapters 1 to 7 offer a valuable supplement to their study. Each chapter contains a brief review of
pertinent topics along with governing equations and laws, with examples inserted to immediately clarify
and emphasize principles as introduced. As in other Schaum’s Outlines, primary emphasis is on the
solution of problems; to this end, over 350 solved problems are presented.
Three principal changes are introduced in the second edition. SPICE method solutions are presented
for numerous problems to better correlate the material with current college class methods. The first-
edition Chapter 13 entitled ‘‘Vacuum Tubes’’ has been eliminated. However, the material from that
chapter relating to triode vacuum tubes has been dispersed into Chapters 4 and 7. A new Chapter 10
entitled ‘‘Switched Mode Power Supplies’’ has been added to give the reader exposure to this important
technology.
SPICE is an acronym for Simulation Program with Integrated Circuit Emphasis. It is commonly
used as a generic reference to a host of circuit simulators that use the SPICE2 solution engine developed
by U.S. government funding and, as a consequence, is public domain software. PSpice is the first
personal computer version of SPICE that was developed by MicroSim Corporation (purchased by
OrCAD, which has since merged with Cadence Design Systems, Inc.). As a promotional tool, Micro-
Sim made available several evaluation versions of PSpice for free distribution without restriction on
usage. These evaluation versions can still be downloaded from many websites. Presently, Cadence
Design Systems, Inc. makes available an evaluation version of PSpice for download by students and
professors at www.orcad.com/Products/Simulation/PSpice/eval.asp.
The presentation of SPICE in this book is at the netlist code level that consists of a collection of
element-specification statements and control statements that can be compiled and executed by most
SPICE solution engines. However, the programs are set up for execution by PSpice and, as a result,
contain certain control statements that are particular to PSpice. One such example is the .PROBE
statement. Probe is the proprietary PSpice plot manager which, when invoked, saves all node voltages
and branch currents of a circuit for plotting at the user’s discretion. Netlist code for problems solved by
SPICE methods in this book can be downloaded at the author’s website www.engr.uky.edu/
cathey.
Errata for this book and selected evaluation versions of PSpice are also available at this website.
The book is written with the assumption that the user has some prior or companion exposure to
SPICE methods in other formal course work. If the user does not have a ready reference to SPICE
analysis methods, the three following references are suggested (pertinent version of PSpice is noted in
parentheses):

Hall, Englewood Cliffs, NJ, 1992, ISBN 0-13-747270-6 (PSpice 4).
