The rapid evolution and explosive growth of integrated circuit technology have had a profound effect on society. Integrated circuits (ICs) are used universally and the expanding use of IC technology requires more accurate circuit analysis methods and tools, prompting the introduction of computers into the design process. The goal of this book is to build a firm foundation in the use of computer-assisted techniques for IC device and process design. Both practical and analytical viewpoints are stressed to give the reader the background necessary to appreciate CAD tools and to feel comfortable with their use. This work presents a discourse on process and device CAD as interrelated subjects, building on a wide range of experiences and applications of the SUPREM program. Chapter 1 focuses on the motivation for coupled process and device CAD. In Chapter 2 SUPREM III is introduced, and process CAD is discussed in terms of ion-implantation, impurity diffusion, and oxidation models. Chapter 3 introduces the Stanford device analysis program SEDAN III (SEmiconductor Device ANalysis).The next three chapters move into greater detail concerning device operating principles and analysis techniques. Chapter 4 reviews the classical formulation of pn junction theory and uses device analysis (SEDAN) both to evaluate some of the classical assumptions and to investigate the difficult problem of high level injection. Chapter 5 returns to MOS devices, reviews the first-order MOS theory, and introduces some important second-order effects. Chapter 6 considers the bipolar transistor. Chapter 7 considers the application of process simulation and device analysis to technology design. The BiCMOS process is selected as a useful design vehicle for two reasons. Firstly, it allows the reader to pull together concepts from the entire book and secondly, the inherent nature of BiCMOS technology offers real constraints and hence trade-offs which must be understood and accounted for.

Phase-Locked Loops Discover the essential materials for phase-locked loop circuit design, from fundamentals to practical design aspects A phase-locked loop (PLL) is a type of circuit with a range of important applications in telecommunications and computing. It generates an output signal with a controlled relationship to an input signal, such as an oscillator which matches the phases of input and output signals. This is a critical function in coherent communication systems, with the result that the theory and design of these circuits are essential to electronic communications of all kinds. Phase-Locked Loops: System Perspectives and Circuit Design Aspects provides a concise, accessible introduction to PLL design. It introduces readers to the role of PLLs in modern communication systems, the fundamental techniques of phase-lock circuitry, and the possible applications of PLLs in a wide variety of electronic communications contexts. The first book of its kind to incorporate modern architectures and to balance theoretical fundamentals with detailed design insights, this promises to be a must-own text for students and industry professionals. The book also features: Coverage of PLL basics with insightful analysis and examples tailored for circuit designersApplications of PLLs for both wireless and wireline systemsPractical circuit design aspects for modern frequency generation, frequency modulation, and clock recovery systemsPhase-Locked Loops is essential for graduate students and advanced undergraduates in integrated circuit design, as well researchers and engineers in electrical and computing subjects.
