Practical Synthesis of High-Performance Analog Circuits presents a technique for automating the design of analog circuits. Market competition and the astounding pace of technological innovation exert tremendous pressure on circuit design engineers to turn ideas into products quickly and get them to market. In digital Application Specific Integrated Circuit (ASIC) design, computer aided design (CAD) tools have substantially eased this pressure by automating many of the laborious steps in the design process, thereby allowing the designer to maximise his design expertise. But the world is not solely digital. Cellular telephones, magnetic disk drives, neural networks and speech recognition systems are a few of the recent technological innovations that rely on a core of analog circuitry and exploit the density and performance of mixed analog/digital ASICs. To maximize profit, these mixed-signal ASICs must also make it to market as quickly as possible. However, although the engineer working on the digital portion of the ASIC can rely on sophisticated CAD tools to automate much of the design process, there is little help for the engineer working on the analog portion of the chip. With the exception of simulators to verify the circuit design when it is complete, there are almost no general purpose CAD tools that an analog design engineer can take advantage of to automate the analog design flow and reduce his time to market. Practical Synthesis of High-Performance Analog Circuits presents a new variation-tolerant analog synthesis strategy that is a significant step towards ending the wait for a practical analog synthesis tool. A new synthesis strategy is presented that can fully automate the path from a circuit topology and performance specifications to a sized variation-tolerant circuit schematic. This strategy relies on asymptotic waveform evaluation to predict circuit performance and simulated annealing to solve a novel non-linear infinite programming optimization formulation of the circuit synthesis problem via a sequence of smaller optimization problems. Practical Synthesis of High-Performance Analog Circuits will be of interest to analog circuit designers, CAD/EDA industry professionals, academics and students.

There has been an increasing demand for Wireless Local Area Network (WLAN) systems in the past few years. New frequency bands are allocated and new standards are being developed to accommodate higher data rates. The fast trend of CMOS scaling has provided an opportunity for the development of low cost integrated WLAN systems. Frequency synthesizers are one of the main building blocks of wireless transceivers. The high frequency digital frequency dividers in a phase-locked loop (PLL) based frequency synthesizer are among the most challenging blocks to design and usually account for a large percentage of the synthesizer total power dissipation. The successful design and integration of a high frequency PLL demands a comprehensive understanding of wireless systems, RF circuits, and loop stability issues. Multi-GHz Frequency Synthesis & Division starts with an overview of WLAN systems and reviews the WLAN market and standards. It then studies PLLs as an essential building block of WLAN receivers, and provides guidelines and engineering recipes for the design of loop filters in high frequency PLLs. Additionally, the book investigates different analog and digital frequency division techniques and introduces injection-locked frequency dividers (ILFDs) as an alternative for conventional frequency dividers. Finally, the book demonstrates a successful design of a fully integrated CMOS frequency synthesizer for a 5 GHz WLAN receiver. Multi-GHz Frequency Synthesis & Division will be of interest to RF and high-speed analog circuit designers and students as well as wireless engineers.

Advanced Low-Power Digital Circuit Techniques presents several novel high performance digital circuit designs that emphasize low-power and low-voltage operation. These circuits represent a wide range of circuits that are used in state-of-the-art VLSI systems and hence serve as good examples for low-power design. Each chapter contains a brief introduction that serves as a quick background and gives the motivation behind the design. Each chapter also ends with a summary that briefly explains the contributions contained therein. This makes the book very readable. The reader can skim through the chapters very quickly to get a feel for the design problems presented in the book and the solutions proposed by the authors. Examples of circuits used in systems where low-power is important from reliability and portability points of view (such as general-purpose and DSP processors) are presented in Chapters 2, 3 and 4. Chapters 5 and 7 give examples of circuits used in systems where reliability and more system integration are the main driving forces behind lowering the power consumption. Chapter 6 gives an example of a general purpose high-performance low-power circuit design. Advanced Low-Power Digital Circuit Techniques is a real designer's book. It investigates alternative circuit styles, as well as architectural alternatives, and gives quantitative results for comparison in realistic technologies. Several of the circuits presented have been fabricated so that simulations can be checked. The circuits covered are the most important building blocks for many designs, so the text will be of direct use to designers. MOS designs are covered, as well as BiCMOS, and there are several novel circuits.

This book discusses in detail the CMOS implementation of energy harvesting. The authors describe an integrated, indoor light energy harvesting system, based on a controller circuit that dynamically and automatically adjusts its operation to meet the actual light circumstances of the environment where the system is placed. The system is intended to power a sensor node, enabling an autonomous wireless sensor network (WSN). Although designed to cope with indoor light levels, the system is also able to work with higher levels, making it an all-round light energy harvesting system. The discussion includes experimental data obtained from an integrated manufactured prototype, which in conjunction with a photovoltaic (PV) cell, serves as a proof of concept of the desired energy harvesting system.

After a brief introduction to low-power VLSI design, the design space of ASIP instruction set architectures (ISAs) is introduced with a special focus on important features for digital signal processing. Based on the degrees of freedom offered by this design space, a consistent ASIP design flow is proposed: this design flow starts with a given application and uses incremental optimization of the ASIP hardware, of ASIP coprocessors and of the ASIP software by using a top-down approach and by applying application-specific modifications on all levels of design hierarchy. A broad range of real-world signal processing applications serves as vehicle to illustrate each design decision and provides a hands-on approach to ASIP design. Finally, two complete case studies demonstrate the feasibility and the efficiency of the proposed methodology and quantitatively evaluate the benefits of ASIPs in an industrial context.

Embedded systems are informally defined as a collection of programmable parts surrounded by ASICs and other standard components, that interact continuously with an environment through sensors and actuators. The programmable parts include micro-controllers and Digital Signal Processors (DSPs). Embedded systems are often used in life-critical situations, where reliability and safety are more important criteria than performance. Today, embedded systems are designed with an ad hoc approach that is heavily based on earlier experience with similar products and on manual design. Use of higher-level languages such as C helps structure the design somewhat, but with increasing complexity it is not sufficient. Formal verification and automatic synthesis of implementations are the surest ways to guarantee safety. Thus, the POLIS system which is a co-design environment for embedded systems is based on a formal model of computation. POLIS was initiated in 1988 as a research project at the University of California at Berkeley and, over the years, grew into a full design methodology with a software system supporting it. Hardware-Software Co-Design of Embedded Systems: The POLIS Approach is intended to give a complete overview of the POLIS system including its formal and algorithmic aspects. Hardware-Software Co-Design of Embedded Systems: The POLIS Approach will be of interest to embedded system designers (automotive electronics, consumer electronics and telecommunications), micro-controller designers, CAD developers and students.

Despite the spectacular breakthroughs of the semiconductor industry, the ability to design integrated circuits under stringent time-to-market requirements is lagging behind integration capacity, so far keeping pace with still valid Moorea (TM)s Law. The resulting gap is threatening with slowing down such a phenomenal growth. The design community believes that it is only by means of powerful CAD tools, design methodologies and even a design paradigm shift, that this design gap can be bridged. In this sense, reuse-based design is seen as a promising solution, and concepts such as IP Block, Virtual Component, and Design Reuse have become commonplace thanks to the significant advances in the digital arena. Unfortunately, the very nature of analog and mixed-signal (AMS) design a "more subtle, hierarchically loose, and handicraft-demandinga" has hindered a similar level of consensus and development.

Aiming at the core of the problem, Reuse Based Methodologies and Tools in the Design of Analog and Mixed-Signal Integrated Circuits presents a framework for the reuse-based design of AMS circuits. The framework is founded on three key elements: (1) a CAD-supported hierarchical design flow that facilitates the incorporation of AMS reusable blocks, reduces the overall design time, and expedites the management of increasing AMS design complexity; (2) a complete, clear definition of the AMS reusable block, structured into three separate facets or views: the behavioral, structural, and layout facets, the first two for top-down electrical synthesis and bottom-up verification, the latter used during bottom-up physical synthesis; (3) the design for reusability set of tools, methods, andguidelines that, relying on intensive parameterization as well as on design knowledge capture and encapsulation, allows to produce fully reusable AMS blocks.

Reuse Based Methodologies and Tools in the Design of Analog and Mixed-Signal Integrated Circuits features a very detailed, tutorial, and in-depth coverage of all issues and must-have properties of reusable AMS blocks, as well as a thorough description of the methods and tools necessary to implement them. For the first time, this has been done hierarchically, covering one by one the different stages of the design flow, allowing us to examine how the reusable block yields its benefits, both in design time and correct performance.

Since the early-1990s, reducing the dynamic switching power has been the main focus in many of the proposed low-power circuit techniques. At that time, the off-state leakage power was negligible compared to dynamic power. However, as technology scales into the deep-submicron regime, the increase in leakage power can no longer be neglected. Soon, the biggest challenge that SoC designers must resolve is the fact that transistors for digital and memory circuits will be more and more leaky as technology generations advance. The semiconductor industry must therefore reduce leakage current in chip designs by two orders of magnitude over the next ten years, or face an interruption in projected chip complexity. Failure to do so would make the mounting leakage current the big stumbling block to Moore's Law. Furthermore, co-operative approaches between computer-aided design development, circuit design, and technology process must be examined. Multi-threshold voltage CMOS (MTCMOS) technology, that has emerged as an increasingly popular technique to control the escalating leakage power, while maintaining high performance. The book addresses the leakage problem in a number of designs for combinational, sequential, dynamic, and current-steering logic. Moreover, computer-aided design methodologies for designing low-leakage integrated circuits are presented. The book give a survey of state-of-the-art techniques presented in the literature as well as proposed designs that minimize leakage power, while achieving high-performance. Multi-Threshold CMOS Digital Circuits Managing Leakage Power is written for students of VLSI design as well as practicing circuit designers, system designers, CAD tool developers and researchers. It assumes a basic knowledge of digital circuit design and device operation, and covers a broad range of circuit design techniques.

This book explores many essential topics in a basic and easy-to-understand manner.

High-Performance CMOS Continuous-Time Filters is devoted to the design of CMOS continuous-time filters. CMOS is employed because the most complex integrated circuits have been realized with this technology for two decades. The most important advantages and drawbacks of continuous-time filters are clearly shown. The transfer function is one of the most important filter parameters but several others (like intermodulation distortion, power-supply rejection ratio, noise level and dynamic range) are fundamental in the design of high-performance systems. Special attention is paid to the practical aspects of the design, which shows the difference between an academic design and an industrial design. A clear understanding of the behavior of the circuits and techniques is preferred over complex equations or interpretation of simulated results. Step-by-step design procedures are very often used to clarify the use of the techniques and topologies. The organization of this text is hierarchical, starting with the design consideration of the basic building blocks and ending with the design of several high-performance continuous-time filters. Most of the circuits have been fabricated, theoretically analyzed and simulated, and silicon measurement results are compared with each other. High-Performance CMOS Continuous-Time Filters can be used as a text book for senior or graduate courses on this topic and can also be useful for industrial engineers as a reference book.

Standard voltages used in today's ICs may vary from about 1.3V to more than 100V, depending on the technology and the application. High voltage is therefore a relative notion. High Voltage Devices and Circuits in Standard CMOS Technologies is mainly focused on standard CMOS technologies, where high voltage (HV) is defined as any voltage higher than the nominal (low) voltage, i.e. 5V, 3.3V, or even lower. In this standard CMOS environment, IC designers are more and more frequently confronted with HV problems, particularly at the I/O level of the circuit. In the first group of applications, a large range of industrial or consumer circuits either require HV driving capabilities, or are supposed to work in a high-voltage environment. This includes ultrasonic drivers, flat panel displays, robotics, automotive, etc. On the other hand, in the emerging field of integrated microsystems, MEMS actuators mainly make use of electrostatic forces involving voltages in the typical range of 30 to 60V. Last but not least, with the advent of deep sub-micron and/or low-power technologies, the operating voltage tends towards levels ranging from 1V to 2.5V, while the interface needs to be compatible with higher voltages, such as 5V. For all these categories of applications, it is usually preferable to perform most of the signal processing at low voltage, while the resulting output rises to a higher voltage level. Solving this problem requires some special actions at three levels: technology, circuit design and layout. High Voltage Devices and Circuits in Standard CMOS Technologies addresses these topics in a clear and organized way. The theoretical background is supported by practical information and designexamples. It is an invaluable reference for researchers and professionals in both the design and device communities.

This book discusses the building blocks of electronic circuits - the microchips, transistors, resistors, condensers, and so forth, and the boards that support them - from the point of view of mechanics: What are the stresses that result from thermal expansion and contraction? What are the elastic parameters that determine whether a component will survive a certain acceleration? After an introduction to the elements of structural analysis and finite-element analysis, the author turns to components, data and testing. A discussion of leadless chip carriers leads to a detailed thermal analysis of pin grid arrays. For compliant leaded systems, both mechanical (bending and twisting) and thermal stresses are discussed in detail. The book concludes with discussions of the dynamic response of circuit cards, plated holes in cards and boards, and the final assembly of cards and boards.

Uncertainty in key parameters within a chip and between different chips in the deep sub micron area plays a more and more important role. As a result, manufacturing process spreads need to be considered during the design process. Quantitative methodology is needed to ensure faultless functionality, despite existing process variations within given bounds, during product development. This book presents the technological, physical, and mathematical fundamentals for a design paradigm shift, from a deterministic process to a probability-orientated design process for microelectronic circuits. Readers will learn to evaluate the different sources of variations in the design flow in order to establish different design variants, while applying appropriate methods and tools to evaluate and optimize their design.
