High-Resolution If-To-Baseband ΣΔ Adc For Car Radios
High-Resolution IF-to-Baseband SigmaDelta ADC for Car Radios addresses the theory, system level design and circuit implementation of a high-resolution continuous-time IF-to-baseband quadrature SigmaDelta ADC. The target application of this ADC is in AM/FM/IBOC car radios. The ADC achieves a dynamic range of 118dB, which eliminates the need for an IF VGA or AM channel filter in car radios.
High-Level Modeling and Synthesis of Analog Integrated Systems
In High-Level Modeling and Synthesis of Analog Integrated Systems, two novel generic behavioral models are described. The first one adopts a time-domain approach and is suited for classes like Delta-Sigma modulators and sampled-data systems. For the second model, a new frequency-domain framework has been developed (the Phase- Frequency Transfer model) which allows the representation of classes of RF systems like front-ends of wireless receivers. To complete the high-level design strategy, the synthesis strategy has been concretized with a new top-down heterogeneous optimization algorithm.

Results of these studies have important implications for estuary resource management and shoreline stability. This book will be of interest to sedimentologists, coastal and Quaternary geologists, environmental scientists, and coastal managers.
Hepatitis Delta Virus ; Vol. 307
Since its discovery nearly 30 years ago, hepatitis delta virus (HDV) has continued to surprise and fascinate. At 1,680 nucleotides the HDV genome is the smallest known to infect man. It is unique among animal viruses, the closest known relatives being plant viroids. To compensate for its limited protein coding capacity, HDV relies heavily on host functions and on structural features of its circular RNA genome. HDV infection depends on hepatitis B virus as a helper, and increases the severity of liver disease caused by HBV alone. There is currently neither an effective HDV vaccine nor a generally accepted useful therapy for HDV infection. This volume encompasses recent developments in HDV research, from molecular virology to genetics to experimental investigation of new therapeutic and vaccine candidates.
Hepatitis Delta Virus ; Medical Intelligence Unit (MIUN)
Hepatitis Delta Virus is an up-to-date guide to hepatitis D virus (HDV), a human virus with a number of distinctive features. Each chapter of this book describes one of the broad aspects of HDV from virology to molecular biology, and from diagnosis to therapy.
Environmental History of the Rhine-Meuse Delta : An ecological story on evolving human–environmental relations coping with climate change and sea-level rise
This book presents the environmental history of the Delta of the lowland rivers Rhine and Meuse, an ecological story on evolving human–environmental relations coping with climate change and sea-level rise. It offers a combination of in-depth ecology and environmental history, dealing with exploitation of land and water, the use of everything nature provided, the development of fisheries and agriculture, changes in biodiversity of higher plants, fish, birds, mammals and invasive exotics. It is the first comprehensive book written in English on the integrated environmental history of the Delta, from prehistoric times up to the present day. It covers the l- acy of human intervention, the inescapable fate of reclaimed, nevertheless subs- ing and sinking polders, ‘bathtubs’ attacked by numerous floods, reclaimed in the Middle Ages and unwittingly exposed to the rising sea level and the increasing amplitude between high and low water in the rivers. The river channels, constricted and regulated between embankments, lost their flood plains, silted up, degraded and incised. Cultivation of raised bog deposits led to oxidation and compacting of peat and clay, resulting in progressive subsidence and flooding; arable land had to be changed into grassland and wetland. For millennia muscular strength and wind and water powers moulded the country into its basic form. From 1800 onwards, acceleration and scaling up by steam power and electricity, and exponential popu- tion growth, resulted in the erection of human structures ‘fixed forever’, and severe pressure on the environment.

Deltas in the Anthropocene
The Anthropocene is the human-dominated modern era that has accelerated social, environmental and climate change across the world in the last few decades. This open access book examines the challenges the Anthropocene presents to the sustainable management of deltas, both the many threats as well as the opportunities.
Continuous-Time Systems
The book systematically covers major foundations of the systems theory. First, the quantitative and qualitative methods of systems description are presented along with the stability analysis. The representation of linear time-invariant systems in the time domain is provided using the convolution, ordinarily differential equations (ODEs), and state space. In the frequency domain, these systems are analyzed using the Fourier and Laplace transforms. The linear time-varying systems are represented using the general convolution, ODEs, and state space. The nonlinear time-invariant systems are described employing the Taylor and Volterra series expansions, ODEs, state space, and approximate methods such as averaging, equivalent linearization, and describing function. Finally, the representation of nonlinear time-varying systems is given using the Taylor and Volterra series, ODEs, modulation functions method, and state space modelling.
Continuous-Time Sigma-Delta A/D Conversion : Fundamentals, Performance Limits and Robust Implementations
This comprehensive book deals with all relevant aspects arising during the analysis, design and simulation of the now widespread continuous-time implementations of sigma-delta modulators. The results of several years of research by the authors in the field of CT sigma-delta modulators are covered, including the analysis and modeling of different CT modulator architectures, CT/DT loop filter synthesis, a detailed error analysis of all components, and possible compensation/correction schemes for the non-ideal behavior in CT sigma-delta modulators. Guidance for obtaining low-power consumption and several practical implementations are also presented. It is shown that all the proposed new theories, architectures and possible correction techniques have been confirmed by measurements on discrete or integrated circuits. Quantitative results are also provided, thus enabling prediction of the resulting accuracy.
CMOS single chip fast frequency hopping synthesizers for Wireless multi-gigahertz applications : Design methodology, analysis, and implementation
Describes an efficient design and characterization methodology that has been developed to study loop trade-offs in both open and close loop modelling techniques. This is based on a simulation platform that incorporates both behavioral models and measured/simulated sub-blocks of the chosen frequency synthesizer. The platform predicts accurately the phase noise, spurious and switching performance of the final design. Therefore excellent phase noise and spurious performance can be achieved while meeting all the specified requirements. The design methodology reduces the need for silicon re-spin enabling circuit designers to directly meet cost, performance and schedule milestones. The developed knowledge and techniques have been used in the successful design and implementation of two high speed multi-mode fractional-N frequency synthesizers for the IEEE 801.11a/b/g standards. Both synthesizer designs are described in details.

CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom : Error Analysis and Practical Design
CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error Analysis and Practical Design starts with a tutorial presentation of the fundamentals of low-pass sigma-delta modulators, their applications, and their most common architectures. It then presents an exhaustive analysis of SC circuit errors with a twofold outcome. On the one hand, compact expressions are derived to support design plans and quick top-down design. On the other, detailed behavioral models are presented to support accurate verification. This set of models allows the designer to determine the required specifications for the different modulator building blocks and form the basis of a systematic design approach. The book is completed in subsequent chapters with the detailed presentation of three high-performance modulator ICs: the first two are intended for DSL-like applications, whereas the third one is intended for automotive sensors.

This design is the first design using the full feedforward Sigma-Delta topology and reaches the highest conversion speed among all the 1-V Sigma-Delta modulators to date.
Lake Taihu, China : Dynamics and Environmental Change
There are many shallow lakes in the world. Many of them play an important socio-economic role as contributors to the drinking water supply, in flood attenuation, fisheries and recreation activities. Because of the current anthropogenic changes in the environment, such lakes rapidly respond to eutrophication and swamping. It is often hard to address these issues because many changes in the ecosystems of shallow lakes are associated with little studied physical processes. This interaction between the aquatic biota and the physical and chemical environment increases the complexity of shallow lake ecosystems. Lake Taihu, located in the delta of Yangtze River, is a typical large, shallow eutrophic lake with area of 2338 km2 and maximum depth of less than 3m . This book provides basic data on various aspects of this lake and summarizes research work on the interaction between its ecology and physical limnology. It will be a reference for teachers and students of freshwater ecology and biology, the aquatic environment in general, and, most strikingly, for all those interested in physical limnology.
