Electronic Principles continues its tradition as a clearly explained in-depth introduction to the electronic principles of semiconductor devices circuits and systems. Written in an easy-to-read conversational style semiconductor devices and circuits are explored including practical applications where they are found. Circuit operation and troubleshooting techniques are “brought to life” with Multisim circuit simulation files found on the associated Online Learning Center. Electronic Principles' subject matter includes updated semiconductor devices and systems including emerging wide bandgap power FETs and an introduction to Industry 4.0. Salient Features: 1. New Chapter 23, “Industry 4.0,” introduces the concepts of the fourth industrial revolution. 2. Extensive coverage of sensors and data conversion, with examples linking semiconductor devices and circuits covered in previous chapters, acts as a capstone chapter that ties the whole textbook together. 3. Expanded material on Multistage Amplifier Troubleshooting using signal tracing and split-half troubleshooting techniques. 4. Listing of correlated lab experiments at the end of each chapter. Much effort has been applied to having the textbook and experiments manual work together as a unified knowledge and performance competency package.
