LTspice developed by Analog Devices is a powerful fast and free SPICE simulator schematic
capture and waveform viewer with a large database of components supported by SPICE models from
all over the world. Drawing a schematic in LTspice is easy and fast. Thanks to its powerful
graphing features you can visualize the voltages and currents in a circuit and also the power
consumption of its components and much more. This book is about learning to design and
simulate electronic circuits using LTspice. Among others the following topics are treated:
DC and AC circuits Signal diodes and Zener diodes Transistor circuits including
oscillators Thyristor SCR diac and triac circuits Operational amplifier circuits
including oscillators The 555 timer IC Filters Voltage regulators Optocouplers
Waveform generation Digital logic simulation including the 74HC family SPICE
modeling LTspice is a powerful electronic circuit simulation tool with many features and
possibilities. Covering them all in detail is not possible in a book of this size. Therefore
this book presents the most common topics like DC and AC circuit analysis parameter sweeping
transfer functions oscillators graphing etc. Although this book is an introduction to
LTspice it covers most topics of interest to people engaged in electronic circuit simulation.
The book is aimed at electronic electrical engineers students teachers and hobbyists. Many
tested simulation examples are given in the book. Readers do not need to have any computer
programming skills but it will help if they are familiar with basic electronic circuit design
and operation principles. Readers who want to dive deeper can find many detailed tutorials
articles videos design files and SPICE circuit models on the Internet. All the
simulation examples used in the book are available on the Elektor website www.elektor.com
20907. Readers can use these example circuits for learning or modify them for their own
applications.
