Linear Electronics

A considerable amount of effort has been devoted, both in industry and academia, towards the design, performance analysis and evaluation of amplification schemes and filters to be used in control systems, audio and video equipment, instrumentation and communication systems.

This book is intended to serve as a complementary textbook for courses dealing with Linear Amplification, but also as a professional book, for engineers who need to update their knowledge in the electronics, control, and communications areas.

The book is suitable for the undergraduate as well as the initial graduate levels of Electrical and Electronics Engineering, Mecatronics, Telecommunications, Automation and Control courses, and is useful for the professional who wants to review or get acquainted with the modern exposition of the amplification theory. The book presents essential concepts in plain language and covers the most important applications of amplifier circuits.

The book has seven chapters, dealing with transistor modeling, linear amplification, types of amplifiers, operational amplifiers, electronic circuits with operational amplifiers, active filters, applications and tests with operational amplifiers and communication circuits.

Four appendices are included: an appendix to detail the operational amplifier model; an appendix with specification data sheets; an appendix on Fourier transform and signal spectrum, including the concepts of convolution; and another one that presents and explains the usual electronics acronyms.

Marcelo Sampaio de Alencar received his bachelor's degree in Electrical Engineering from Universidade Federal de Pernambuco (UFPE), Brazil, 1980; his master's degree in Electrical Engineering from Universidade Federal da Paraiba (UFPB), Brazil, 1988; and his Ph.D. from the University of Waterloo, Canada, 1994. He worked for the Department of Electrical Engineering, Federal University of Paraiba (UFPB); for the Federal University of Campina Grande (UFCG); for the State University of Santa Catarina (UDESC); and for the Federal University of Bahia (UFBA). He was visiting professor atthe University of Toronto and is now visiting professor at the Senai Cimatec, Salvador, Brazil. He is founder and President of the Institute for Advanced Studies in Communications (Iecom). He has been awarded several scholarships and grants from the Brazilian National Council for Scientific and Technological Research (CNPq), from the IEEE Foundation, from the University of Waterloo, and from the Federal University of Paraiba. He received an achievement award from the Brazilian Telecommunications Society (SBrT), an award from the Medicine College of the Federal University of Campina Grande (UFCG), and an achievement award from the College of Engineering of the Federal University of Pernambuco. He published over 500 engineering and scientific papers and 26 books. He also wrote chapters for 12 books. He served on the Board of Directors of SBrT and on the SBMO Council. He is a Registered Professional Engineer, and he was a columnist for the traditional Brazilian newspaper Jornal do Commercio. He is a laureate of the prestigious 2014 Attilio Giarola Medal of the Brazilian Microwave and Optoelectronics Society (SBMO).
