The tremendous growth in wireless and mobile communications has placed stringent requirements on channel spacing and, by implication, on the phase noise of oscillators. Compounding the challenge has been a recent drive toward implementations of transceivers in CMOS, whose inferior l/f noise performance has usually been thought to disqualify it from use in all but the lowest-performance oscillators. Low noise oscillators are also highly desired in the digital world. The continued drive toward higher clock frequencies translates into a demand for ever-decreasing jitter. There is a need for a deep understanding of the fundamental mechanisms governing the process by which device, substrate, and supply noise turn into jitter and phase noise. Existing models generally offer only qualitative insights, however, and it has not always been clear why they are not quantitatively correct. The Design of Low Noise Oscillators offers a new time-variant phase noise model. By discarding the implicit assumption of time- invariance underlying many other approaches, this model is capable of making quantitative predictions of the phase noise and jitter of different types of oscillators. It is able to attribute a definite amount of phase noise to every noise source in the circuit. Because of its time-variant nature, the model also takes into account the effect of cyclostationary noise sources in a natural way. It details the precise mechanism by which low frequency noise, such as l/f noise, upconverts into close-in phase noise. An important new understanding is that rise and fall time symmetry controls such upconversion. More important, it suggests practical methods for suppressing this upconversion, so thatgood oscillators can be built in technologies with notoriously poor l/f noise performance (such as CMOS or GaAs MESFET). The Design of Low Noise Oscillators will be of interest to both analog and digital circuit as well as RF circuit designers.
"Optimal Design of Distributed Control and Embedded Systems "focuses on the design of special control and scheduling algorithms based on system structural properties as well as on analysis of the influence of induced time-delay on systems performances. It treats the optimal design of distributed and embedded control systems (DCESs) with respect to communication and calculation-resource constraints, quantization aspects, and potential time-delays induced by the associated communication and calculation model. Particular emphasis is put on optimal control signal scheduling based on the system state. In order to render this complex optimization problem feasible in real time, a time decomposition is based on periodicity induced by the static scheduling is operated. The authors present a co-design approach which subsumes the synthesis of the optimal control laws and the generation of an optimal schedule of control signals on real-time networks as well as the execution of control tasks on a single processor. The authors also operate a control structure modification or a control switching based on a thorough analysis of the influence of the induced time-delay system influence on stability and system performance in order to optimize DCES performance in case of calculation and communication resource limitations. Although the richness and variety of classes of DCES preclude a completely comprehensive treatment or a single best method of approaching them all, this co-design approach has the best chance of rendering this problem feasible and finding the optimal or some sub-optimal solution. The text is rounded out with references to such applications as car suspension and unmanned vehicles. "Optimal Design of Distributed Control and Embedded Systems" will be of most interest to academic researchers working on the mathematical theory of DCES but the wide range of environments in which they are used also promotes the relevance of the text for control practitioners working in the avionics, automotive, energy-production, space exploration and many other industries."
A recent technological advance is the art of designing circuits to test themselves, referred to as a Built-In Self-Test. This book is written from a designer's perspective and describes the major BIST approaches that have been proposed and implemented, along with their advantages and limitations.
As the trend to system-on-chip solutions gradually consolidates,
including an ever-increasing usage of digital signal processing, a
concurrent enhancement of the analog front-end performance is
required. Moreover, such enhanced performances must be achieved
under the constraints imposed by digitally driven technology
roadmaps, with low-voltage supplies, poor-performance (and often
badly characterized) devices ... and above all the unavoidable
presence of noisy digital circuits. It is under the pressure of
these challenges that analog designers must sharpen their wits to
overcome the problems. Supported by both designers' ingenuity and
slow, but precious, improvements of digital CMOS technologies, the
results of recent research confirm that solutions can be found.

Automatic Modulation Classification (AMC) has been a key technology in many military, security, and civilian telecommunication applications for decades. In military and security applications, modulation often serves as another level of encryption; in modern civilian applications, multiple modulation types can be employed by a signal transmitter to control the data rate and link reliability. This book offers comprehensive documentation of AMC models, algorithms and implementations for successful modulation recognition. It provides an invaluable theoretical and numerical comparison of AMC algorithms, as well as guidance on state-of-the-art classification designs with specific military and civilian applications in mind. Key Features: * Provides an important collection of AMC algorithms in five major categories, from likelihood-based classifiers and distribution-test-based classifiers to feature-based classifiers, machine learning assisted classifiers and blind modulation classifiers * Lists detailed implementation for each algorithm based on a unified theoretical background and a comprehensive theoretical and numerical performance comparison * Gives clear guidance for the design of specific automatic modulation classifiers for different practical applications in both civilian and military communication systems * Includes a MATLAB toolbox on a companion website offering the implementation of a selection of methods discussed in the book
This book presents innovative solutions in the design of precision instrumentation amplifier and read-out ICs, which can be used to boost millivolt-level signals transmitted by modern sensors, to levels compatible with the input ranges of typical Analog-to-Digital Converters (ADCs). The discussion includes the theory, design and realization of interface electronics for bridge transducers and thermocouples. It describes the use of power efficient techniques to mitigate low frequency errors, resulting in interface electronics with high accuracy, low noise and low drift. Since this book is mainly about techniques for eliminating low frequency errors, it describes the nature of these errors and the associated dynamic offset cancellation techniques used to mitigate them."
This practical guide and introduction to the design of key RF building blocks used in high data rate transmitters emphasizes CMOS circuit techniques applicable to oscillators and upconvertors. The book is written in an easily accessible manner, without losing detail on the technical side.
Fine pitch high lead count integrated circuit packages represent a dramatic change from the conventional methods of assembling electronic components to a printed interconnect circuit board. To some, these FPTpackages appear to bean extension of the assembly technology called surface mount or SMT. Many of us who have spent a significant amount of time developing the process and design techniques for these fine pitchpackages haveconcluded that these techniquesgobeyondthose commonly useed for SMT. In 1987 the presentauthor, convincedofthe uniqueness ofthe assembly and design demands ofthese packages, chaired ajoint committee where the members agreed to use fine pitch technology (FPT) as the defining term for these demands. The committee was unique in several ways, one being that it was the first time three U. S. standards organizations, the IPC (Lincolnwood, IL), theEIA(Washington, D. C. ), and theASTM (Philadelphia), cametogether tocreate standards before a technology was in high demand. The term fine pitch technology and its acronym FPT have since become widely accepted in the electronics industry. The knowledge of the terms and demands of FPT currently exceed the usage of FPT packaged components, but this is changing rapidly because of the size, performance, and cost savings of FPT. I have resisted several past invitations to write other technical texts. However, I feel there are important advantages and significant difficulties to be encountered with FP
Despite the fact that in the digital domain, designers can take full benefits of IPs and design automation tools to synthesize and design very complex systems, the analog designers' task is still considered as a 'handcraft', cumbersome and very time consuming process. Thus, tremendous efforts are being deployed to develop new design methodologies in the analog/RF and mixed-signal domains. This book collects 16 state-of-the-art contributions devoted to the topic of systematic design of analog, RF and mixed signal circuits. Divided in the two parts Methodologies and Techniques recent theories, synthesis techniques and design methodologies, as well as new sizing approaches in the field of robust analog and mixed signal design automation are presented for researchers and R/D engineers.

Systematic Design of Sigma-Delta Analog-to-Digital Converters
describes the issues related to the sigma-delta analog-to-digital
converters (ADCs) design in a systematic manner: from the top level
of abstraction represented by the filters defining signal and noise
transfer functions (STF, NTF), passing through the architecture
level where topology-related performance is calculated and
simulated, and finally down to parameters of circuit elements like
resistors, capacitors, and amplifier transconductances used in
individual integrators. The systematic approach allows the
evaluation of different loop filters (order, aggressiveness,
discrete-time or continuous-time implementation) with quantizers
varying in resolution. Topologies explored range from simple single
loops to multiple cascaded loops with complex structures including
more feedbacks and feedforwards. For differential circuits, with
switched-capacitor integrators for discrete-time (DT) loop filters
and active-RC for continuous-time (CT) ones, the passive integrator
components are calculated and the power consumption is estimated,
based on top-level requirements like harmonic distortion and noise
budget.
The purpose of this book is to survey the state of the art and evolving directions in post-silicon and runtime verification. The authors start by giving an overview of the state of the art in verification, particularly current post-silicon methodologies in use in the industry, both for the domain of processor pipeline design and for memory subsystems. They then dive into the presentation of several new post-silicon verification solutions aimed at boosting the verification coverage of modern processors, dedicating several chapters to this topic. The presentation of runtime verification solutions follows a similar approach. This is an area of processor design that is still in its early stages of exploration and that holds the promise of accomplishing the ultimate goal of achieving complete correctness guarantees for microprocessor-based computation. The authors conclude the book with a look towards the future of late-stage verification and its growing role in the processor life-cycle.
CMOS Memory Circuits is a systematic and comprehensive reference work designed to aid in the understanding of CMOS memory circuits, architectures, and design techniques. CMOS technology is the dominant fabrication method and almost the exclusive choice for semiconductor memory designers. Both the quantity and the variety of complementary-metal-oxide-semiconductor (CMOS) memories are staggering. CMOS memories are traded as mass-products worldwide and are diversified to satisfy nearly all practical requirements in operational speed, power, size, and environmental tolerance. Without the outstanding speed, power, and packing density characteristics of CMOS memories, neither personal computing, nor space exploration, nor superior defense systems, nor many other feats of human ingenuity could be accomplished. Electronic systems need continuous improvements in speed performance, power consumption, packing density, size, weight, and costs. These needs continue to spur the rapid advancement of CMOS memory processing and circuit technologies. CMOS Memory Circuits is essential for those who intend to (1) understand, (2) apply, (3) design and (4) develop CMOS memories.
With the development of Very-Deep Sub-Micron technologies, process variability is becoming increasingly important and is a very important issue in the design of complex circuits. Process variability is the statistical variation of process parameters, meaning that these parameters do not have always the same value, but become a random variable, with a given mean value and standard deviation. This effect can lead to several issues in digital circuit design. The logical consequence of this parameter variation is that circuit characteristics, as delay and power, also become random variables. Because of the delay variability, not all circuits will now have the same performance, but some will be faster and some slower. However, the slowest circuits may be so slow that they will not be appropriate for sale. On the other hand, the fastest circuits that could be sold for a higher price can be very leaky, and also not very appropriate for sale. A main consequence of power variability is that the power consumption of some circuits will be different than expected, reducing reliability, average life expectancy and warranty of products. Sometimes the circuits will not work at all, due to reasons associated with process variations. At the end, these effects result in lower yield and lower profitability. To understand these effects, it is necessary to study the consequences of variability in several aspects of circuit design, like logic gates, storage elements, clock distribution, and any other that can be affected by process variations. The main focus of this book will be storage elements.

This comprehensive and insightful book discusses ESD protection circuit design problems from an IC designer's perspective. On-Chip ESD Protection for Integrated Circuits: An IC Design Perspective provides both fundamental and advanced materials needed by a circuit designer for designing ESD protection circuits, including:
The interest for :I:~ modulation-based NO converters has significantly increased in the last years. The reason for that is twofold. On the one hand, unlike other converters that need accurate building blocks to obtain high res olution, :I:~ converters show low sensitivity to the imperfections of their building blocks. This is achieved through extensive use of digital signal pro cessing - a desirable feature regarding the implementation of NO interfaces in mainstream CMOS technologies which are better suited for implementing fast, dense, digital circuits than accurate analog circuits. On the other hand, the number of applications with industrial interest has also grown. In fact, starting from the earliest in the audio band, today we can find :I:~ converters in a large variety of NO interfaces, ranging from instrumentation to commu nications. These advances have been supported by a number of research works that have lead to a considerably large amount of published papers and books cov ering different sub-topics: from purely theoretical aspects to architecture and circuit optimization. However, so much material is often difficultly digested by those unexperienced designers who have been committed to developing a :I:~ converter, mainly because there is a lack of methodology. In our view, a clear methodology is necessary in :I:~ modulator design because all related tasks are rather hard.
Although exploratory and developmental activity in electron beam testing (EBT) 25 years, it was not had already been in existence in research laboratories for over until the beginning of the 1980s that it was taken up seriously as a technique for integrated circuit (IC) testing. While ICs were being fabricated on design rules of several microns, the mechanical ne edle probe served quite adequately for internal chip probing. This scenario changed with growing device complexity and shrinking geometries, prompting IC manufacturers to take note ofthis new testing technology. It required several more years and considerable investment by electron beam tester manufacturers, however, to co me up with user-friendly automated systems that were acceptable to IC test engineers. These intervening years witnessed intense activity in the development of instrumentation, testing techniques, and system automation, as evidenced by the proliferation of technical papers presented at conferences. With the shift of interest toward applications, the technology may now be considered as having come of age.
