For instance, the accomplishment of target specifi ca- tions requires the highest experience of analog designers along with their creativity and ingenuity to deal with trade-off s and to discover the obscure interactions among design parameters. From this point of view, analog circuit design is considered a kind of art. To enhance analog circuit’s performances, a designer very o en applies rules of thumb, making almost impossible the development of systematic or generic design receipts, in part because there exist a very huge plethora of circuit topologies and each one requires diff erent design strategies. Fortunately, researchers around the world share acquired experience and insights to introduce advances in analog circuit design, mod- eling, simulation and optimization. That way, this book summarizes recent advances in analog circuits, covering a wide range of topics from circuit theory to multidisci- plinary applications. The key contribution of each chapter focus on recent advances in analog circuits, open issues and new challenges to accomplish academic or industrial target specifi cations. Electronic design automation of analog circuits is presented in Chapter 1 for low-pow- er applications. The appropriate biasing is covered in Chapter 2, and it is extended to new port modeling and local biasing of analog components in Chapter 3. In Chapter 4 a behavioral modeling approach at a level of abstraction higher than the transistor one for mixed-mode circuits, is introduced. The following chapters introduce novel design issues. For instance, Chapter 5 presents a hierarchical harmonic balance for analog and RF circuit simulation. This chapter is much focused on design automation challenges, as well as Chapter 6 to yield optimization of analog circuits considering process varia- tions and parameter degradation. Chapter 7 shows the application of interval analysis techniques for linear analog circuit’s problems. When analog circuits co-exist with digital ones they process mixed-signals, as shown in Chapter 8 for CMOS integrated circuits. Chapter 9 presents the application of nano- scale DG-MOSFETs for tunable analog and reconfi gurable digital circuits. Nanotech- nology needs the application of statistical simulation, as shown in Chapter 10. Chapter 11 presents advanced statistical methodologies for tolerance analysis. Analog circuits applications like the analog-aware circuit schematic synthesis, is shown in Chapter 12. Sizing is a very complex topic and an SQP and branch-and-bound based X Preface approach is presented in Chapter 13. Chapters 14 and 15 introduce analog circuits for motion detection applied to target tracking system, and for implementing a critical temperature sensor based on excitable neuron models, respectively. Chapter 16 fi nally discusses evolvable metaheuristics on circuit design. Enjoy the book! Esteban Tlelo-Cuautle INAOE Department of Electronics Mexico .
