Information Macrodynamics (IMD) belong to an interdisciplinary science that represents a new theoretical and computer-based methodology for a system informational descriptionand improvement,including various activities in such areas as thinking, intelligent processes, communications, management, and other nonphysical subjects with their mutual interactions, informational superimposition, and theinformation transferredbetweeninteractions. The IMD is based on the implementation of a single concept by a unique mathematical principle and formalism, rather than on an artificial combination of many arbitrary, auxiliary concepts and/or postulates and different mathematical subjects, such as the game, automata, catastrophe, logical operations theories, etc. This concept is explored mathematically using classical mathematics as calculus of variation and the probability theory, which are potent enough, without needing to developnew,specifiedmathematical systemicmethods. The formal IMD model automatically includes the related results from other fields, such as linear, nonlinear, collective and chaotic dynamics, stability theory, theory of information, physical analogies of classical and quantum mechanics, irreversible thermodynamics, andkinetics. The main IMD goal is to reveal the information regularities, mathematically expressed by the considered variation principle (VP), as a mathematical tool to extractthe regularities and define the model, whichdescribes theregularities. The IMD regularities and mechanisms are the results of the analytical solutions and are not retained by logical argumentation, rational introduction, and a reasonable discussion. The IMD's information computer modeling formalism includes a human being (as an observer, carrier and producer ofinformation), witha restoration of the model during the objectobservations.

Design of Multi-Bit Delta-Sigma A/D Converters discusses both architecture and circuit design aspects of Delta-Sigma A/D converters, with a special focus on multi-bit implementations. The emphasis is on high-speed high-resolution converters in CMOS for ADSL applications, although the material can also be applied for other specification goals and technologies. Design of Multi-Bit Delta-Sigma A/D Converters starts with a general introduction of the concepts of Delta-Sigma converters. A wide variety of architectures are discussed, ranging from single-loop to cascaded and various multi-bit topologies. These topologies are optimized to obtain stable converters with a high accuracy. A clear overview is provided of the maximum achievable performance of each topology, which allows a designer to select the optimal architecture for a certain specification. Special attention is paid to multi-bit architectures and possible solutions for the linearity problem of the DA converter in the feedback loop of converters. Several circuit design aspects of multi-bit Delta-Sigma converters are discussed. Various models are provided for a wide range of linear and non-linear circuit imperfections, which can degrade the performance of the converter. These models allow the designer to determine the required specifications for the different building blocks and form the basis of a systematic design procedure. The presented material is combined in a concluding chapter, which illustrates the systematic design procedure for two high-performance converters. Design of Multi-Bit Delta-Sigma A/D Converters provides a clear comparison of architectures and yields insight into the influence of the most important circuit non-idealities. It will allow you to design robust and high-performance Delta-Sigma AD converters in a shorter time. It is essential reading for analog design engineers and researchers in the field of AD converters and it is also suitable as a text for an advanced course on the subject.

CMOS Cellular Receiver Front-Ends: From Specification to Realization deals with the design of the receive path of a highly-integrated CMOS cellular transceiver for the GSM-1800 cellular system. The complete design trajectory is covered, starting from the documents describing the standard down to the systematic development of CMOS receiver ICs that comply to the standard. The design of CMOS receivers is tackled at all abstraction levels: from architecture level, via circuit level, down to the device level, and the other way around. Different receiver architectures are compared with respect to integratability, achievable performance and required building block specifications. The requirements of the GSM-1800 standard are mapped onto a set of measurable specifications for a highly-integrated low-IF receiver and distributed among the different building blocks. Several circuit topologies are presented that realize the main functions of the receive path. The dynamics of the elementary specifications of these circuits are explained in terms of the operating point of the involved devices. Wherever possible, this is done using analytical expressions. Based on these insights, detailed sizing procedures are developed to systematically size these RF circuits for a set of specifications. The feasibility of meeting the requirements of today's high-end cellular standards is demonstrated in a mainstream submicron CMOS technology by the development of two highly-integrated GSM-1800 receivers. The theoretical core of the book discusses the fundamental and more advanced aspects of RF CMOS design. It focuses specifically on all aspects of the design of high-performance CMOS low-noise amplifiers. Attempts are made to reconcile the analog designer's and the RF designer's point of view on how to look at submicron CMOS transistors. Special attention is given to the fallacies and pitfalls of input matching in a CMOS context. A methodology for the systematic design of CMOS low-noise amplifie

From the Publisher: "Geographic Location in the Internet discusses how to find the location of mobile devices in the wireless Internet, specifically those that involve the determination of the geographic location of mobile devices. 2G systems of GSM, GPRS and 3G systems of UMTS and cdma2000, and other link technologies and an extensive description on how numerical location of the mobile can be tracked real-time also are discussed." Geographic Location in the Internet is intended for engineers, developers and designers involved in technical work related to mobile networking and mobile computing. It can also be used in graduate level courses on geographic location and location-based systems.
