Books
by Thomas R. Cuthbert, Ph.D.
I have written three books. The following briefly describes my motivation, and much more detail is available by using the buttons to the left.
Circuit Design Using Personal Computers. Published by John Wiley in New York in 1983, republished by Krieger Publishing in Florida in 1994, and republished by Cuthbert in Arkansas in 1996. I wrote this book to show how useful personal computers can be in circuit design. That was an issue in 1987, but it is certainly granted in the new millennium. However, this book contains a wide range of very useful design techniques, and the related software still provides concise aid in computing useful answers. My first goal was to describe practical RF circuit design techniques that are especially appropriate for personal computers and have one or more fundamental concepts or applications. My second goal was to exploit the interaction between circuit designer and computer to clarify both design techniques and fundamental concepts.
Optimization Using Personal Computers with Applications to Electrical Networks. Published by John Wiley in New York in 1987 and republished by Cuthbert in Arkansas in 1998. I wrote this book because optimization is an astoundingly useful tool in RF circuit design. My first goal was to explain the mathematical basis of optimization, using iterative algorithms on a personal computer to obtain key insights and to learn by performing the computations. The second goal was to acquaint the reader with the more successful gradient optimization techniques, especially Gauss-Newton and quasi-Newton methods with nonlinear constraints. The third goal was to help the reader develop the ability to read and comprehend the essential content of the vast amount of optimization literature. The last goal was to present programs and examples that illustrate the ease of obtaining exact gradients (first partial derivatives) for response functions of linear electrical networks and their analogues in the physical sciences.
Broadband Direct-Coupled and Matching RF Networks. Published by Cuthbert in Arkansas in 1999. I wrote this book to report my research results obtained in the 1990's. These design techniques are presented at a level between the valuable one-to-one contact in my seminars and the practical but graduate-level treatment in my prior two books. My more important discoveries have been new and useful methods for design of broadband direct-coupled and matching RF networks, both supported by effective design software. The material is organized to support the orderly development of these topics in my seminars.
