Semiconductor Circuits: Theory, Design and Experiment focuses on the design and modification of circuits involving transistors and related semiconductor devices. This book is divided into three parts. The four chapters of Part I are concerned with the physical theory of semiconductors; production of pn junctions; and characteristics and equivalent circuits of transistors. The treatment of physical theory is briefly mentioned. Part II forms the major portion of this book and is made up of seven chapters. These chapters have been written at a practical level, including a number of complete circuit designs. Chapters 10 and 11, in particular, deal with the aspects of semiconductors. Several laboratory demonstrations and experiments with semiconductors are provided in Part III. This publication is written as an undergraduate and technical college textbook that helps electrical engineering students in choosing the right component and device for a particular application.

Semiconductor Circuits: Worked Examples is a companion volume to Semiconductor Circuits: Theory, Design and Experiment. This book is a presentation of many questions at the undergraduate and technical level centering on the transistor. The problems concern basic physical theories of energy bands, covalent bond, and crystal lattice. Questions regarding the intrinsic property and impurity of semiconductors are also asked after the book presents a brief discussion of semiconductors. This book addresses the physical principles of semiconductor devices by presenting questions and worked examples on the pn junction, the effect of impurity content on a pn junction, and the pnp transistor. Other problems presented in the book pertain to the construction and characteristics of transistors, equivalent circuits, voltage amplifiers, and power amplifiers. Some problems require the students to make sketches of circuitry, for example, that of an LC transistor oscillator; while other problems require the student to draw and discuss the circuit of three-input AND gate, using diodes. This book then gives a couple of problems on special applications concerning the diode. This text is suitable for teachers and students of technical courses, especially those concerned with electronic circuitry.

Signal Flow Analysis provides information pertinent to the fundamental aspects of signal flow analysis. This book discusses the basic theory of signal flow graphs and shows their relation to the usual algebraic equations. Organized into seven chapters, this book begins with an overview of properties of a flow graph. This text then demonstrates how flow graphs can be applied to a wide range of electrical circuits that do not involve amplification. Other chapters deal with the parameters as well as circuit applications of transistors. This book discusses as well the variety of circuits using thermionic valves or vacuum tubes. The final chapter deals with the application of the flow graph to find the equation of motion of an electrical meter movement where the feedback is mechanical. This book is intended to be suitable for the undergraduate engineering students, in a middle of a degree or diploma course, or for the practicing engineer who wishes to obtain a speedy solution to an electrical problem.
