Design and Analysis of High Efficiency Line Drivers for xDSL covers the most important building block of an xDSL (ADSL, VDSL, ...) system: the line driver. Traditional Class AB line drivers consume more than 70% of the total power budget of state-of-the-art ADSL modems. This book describes the main difficulties in designing line drivers for xDSL. The most important specifications are elaborated staring from the main properties of the channel and the signal properties. The traditional (class AB), state-of-the-art (class G) and future technologies (class K) are discussed. The main part of Design and Analysis of High Efficiency Line Drivers for xDSL describes the design of a novel architecture: the Self-Oscillating Power Amplifier or SOPA.
This book fits in the quest for highly efficient fully integrated xDSL modems for central office applications. It presents a summary of research at one of Europe’s most famous analog design research groups over a five year period. The book focuses on the line driver, the most demanding building block of the xDSL modem for lowering power. The book covers the total design flow of monolithic CMOS high voltage circuits. It is essential reading for analog design engineers.
Thanks to the advance of semiconductor and communication technology, the wireless communication market has been booming in the last two decades. It evolved from simple pagers to emerging third-generation (3G) cellular phones. In the meanwhile, broadband communication market has also gained a rapid growth. As the market always demands hi- performance and low-cost products, circuit designers are seeking hi- integration communication devices in cheap CMOS technology. The phase-locked loop frequency synthesizer is a critical component in communication devices. It works as a local oscillator for frequency translation and channel selection in wireless transceivers and broadband cable tuners. It also plays an important role as the clock synthesizer for data converters in the analog-and-digital signal interface. This book covers the design and analysis of PLL synthesizers. It includes both fundamentals and a review of the state-of-the-art techniques. The transient analysis of the third-order charge-pump PLL reveals its locking behavior accurately. The behavioral-level simulation of PLL further clarifies its stability limit. Design examples are given to clearly illustrate the design procedure of PLL synthesizers. A complete derivation of reference spurs in the charge-pump PLL is also presented in this book. The in-depth investigation of the digital CA modulator for fractional-N synthesizers provides insightful design guidelines for this important block.
To meet the demands of today's highly competitive market, analog electronics designers must develop their IC designs in a minimum of time. The difference between first- and second-time right seriously affects a company's share of the market. Analog designers are therefore in need for structured design methods together with the theory and tools to support them, especially when pushing the performance limits in high-performance designs. Systematic Modeling and Analysis of Telecom Frontends and Their Building Blocks aims to help designers in speeding up telecommunication frontend design by offering an in-depth understanding of the frontend's behavior together with methods and algorithms that support designers in bringing this understanding to practice. The book treats topics such as time-varying phase-locked loop stability, noise in mixing circuits, oscillator injection locking, oscillator phase noise behavior, harmonic oscillator dynamics and many more. In doing so, it always starts from a theoretical foundation that is both rigorous and general. Phase-locked loop and mixer analysis, for example, are grounded upon a general framework for time-varying small-signal analysis. Likewise, analysis of harmonic oscillator transient behavior and oscillator phase noise analysis are treated as particular applications of a general framework for oscillator perturbation analysis. In order to make the book as easy to read as possible, all theory is always accompanied by numerous examples and easy-to-catch intuitive explanations. As such, the book is suited for both computer-aided design engineers looking for general theories and methods, either as background material or for practical implementation in tools, as well as for practicing circuit designers looking for help and insight in dealing with a particular application or a particular high-performance design problem.
Design of Wireless Autonomous Dataloggers IC's reveals the state of the art in the design of complex dataloggers, with a special focus on low power consumption. The emphasis is on autonomous dataloggers for stand-alone applications with remote reprogrammability. The book starts with a comprehensive introduction on the most important design aspects and trade-offs for miniaturized low-power telemetric dataloggers. After the general introduction follows an in-depth case study of an autonomous CMOS datalogger IC for the registration of in vivo loads on oral implants. After tackling the design of the datalogger on the system level, the design of the different building blocks is elaborated in detail, with emphasis on low power. A clear overview of the operation, the implementation, and the most important design considerations of the building blocks to achieve optimal system performance is given. Design of Wireless Autonomous Dataloggers IC's discusses the design of correlated double sampling amplifiers and sample-and-holds, binary-weighted current steering DACs, successive approximation ADCs and relaxation clock oscillators and can also be used as a manual for the design of these building blocks. Design of Wireless Autonomous Dataloggers IC's covers the complete design flow of low-power miniaturized autonomous dataloggers with a bi-directional wireless link and on-board data processing, while providing detailed insight into the most critical design issues of the different building blocks. It will allow you to design complex dataloggers faster. It is essential reading for analog design engineers and researchers in the field of miniaturized dataloggers and is also suitable as a text for an advanced course on the subject.
The book gives an overview of the state-of-the-art in SigmaDelta design and of the challenges for future realizations. It provides an understanding of the fundamental power efficiency of SigmaDelta converters. In addition, it presents an analysis of the power consumption in the decimation filter. Understanding these power/performance trade-offs, it becomes clear that straight-forward digitization of a conditioning channel, i.e. exchanging analog for digital conditioning, comes at a major power penalty.
Institutional book, not really for bookstore catalogue The book contains valuable information structured to provide insight on how to design SC sigma-delta modulators. It presents architectures, circuits, models, methods and practical considerations for the design of high-performance low-pass switched-capacitor (SC) sigma-delta A/D interfaces for mixed-signal CMOS ASICs. The main focus of the book is on cascade architectures. It differs from other books in the complete, in-depth coverage of SC circuit errors.
