Preface

The aim of this book is not to let the readers drowned into a sea of computations. More hopefully, it aims to inspire the readers with mind and strength to make full use of the MATLAB and PSpice softwares so that they can feel comfortable with mathematical equations without caring about how to solve them and further can enjoy developing their ability to analyze/design electronic circuits. It aims also to present the readers with a steppingstone to radio frequency (RF) circuit design from junior–senior level to senior‐graduate level by demonstrating how MATLAB can be used for the design and implementation of microstrip filters. The features of this book can be summarized as follows:

1. For representative examples of designing/analyzing electronic circuits, the analytical solutions are presented together with the results of MATLAB design and analysis (based on the theory) and PSpice simulation (similar to the experiment) in the form of trinity. This approach gives the readers not only information about the state of the art, but also confidence in the legitimacy of the solution as long as the solutions obtained by using the two software tools agree with each other.
2. For representative examples of impedance matching and filter design, the solution using MATLAB and that using Smith chart have been presented for comparison/crosscheck. This approach is expected to give the readers not only confidence in the legitimacy of the solution, but also deeper understanding of the solution.
3. The purposes of the two softwares, MATLAB and PSpice, seem to be overlapped and it is partly true. However, they can be differentiated since MATLAB is mainly used to design circuits and perform a preliminary analysis of (designed) circuits while PSpice is mainly used for detailed and almost real‐world simulation of (designed) circuits.
4. Especially, it presents how to use MATLAB and PSpice not only for designing/analyzing electronic and RF circuits but also for understanding the underlying processes and related equations without having to struggle with time‐consuming/error‐prone computations.

The contents of this book are derived from the works of many (known or unknown) great scientists, scholars, and researchers, all of whom are deeply appreciated. We would like to thank the reviewers for their valuable comments and suggestions, which contribute to enriching this book.

We also thank the people of the School of Electronic and Electrical Engineering, Chung‐Ang University for giving us an academic environment. Without affections and supports of our families and friends, this book could not be written. We gratefully acknowledge the editorial, Brett Kurzman and production staff of John Wiley & Sons, Inc. including Project Editor Antony Sami and Production Editor Viniprammia Premkumar for their kind, efficient, and encouraging guide.
