Average Reviews:
(More customer reviews)This is a quite useful book for anyone who needs to deal with power consumption in portable devices, sensor networks, or other low-power applications. The book covers a broad array of topics: transistor process technology, ASIC design methodology for low-power circuits, software optimization, batteries, regulators, and displays. For the reader who is generally familiar with embedded systems, this book is a very nice quick way to catch up on what's being done in all the aspects of power-sensitive system design. While the material is not terribly deep or mathematical, some background in electrical and/or software engineering is needed to benefit from many of the discussions. A nice list of references is provided at the end of each chapter.
Cavils are mostly minor. The book is stylistically disfigured by a number of incomplete and ungrammatical sentences. Some passages read as if they were lifted directly from vendor sales collateral; it would have been nice to have the author's critical evaluation of products rather than or in addition to the vendor's marketing materials. In some of the circuit diagrams, boxes are used for resistors and/or inductors, instead of the standard symbols -- minor but irritating. The introductory chapters are somewhat awkward and repetitive, but most readers will already be familiar with the problems of power use in portable devices (that's why they are reading the book), so they don't really need this material anyway.

Sealed Lead Acid.Nickel Cadmium.Lithium Ion.How do you balance battery life with performance and cost?This book shows you how!Now that "mobile" has become the standard, the consumer not only expects mobility but demands power longevity in wireless devices. As more and more features, computing power, and memory are packed into mobile devices such as iPods, cell phones, and cameras, there is a large and growing gap between what devices can do and the amount of energy engineers can deliver. In fact, the main limiting factor in many portable designs is not hardware or software, but instead how much power can be delivered to the device. This book describes various design approaches to reduce the amount of power a circuit consumes and techniques to effectively manage the available power.Power Management Advice On:.Low Power Packaging Techniques.Power and Clock Gating.Energy Efficient Compilers.Various Display Technologies.Linear vs. Switched Regulators.Software Techniques and Intelligent Algorithms* Addresses power versus performance that each newly developed mobile device faces* Robust case studies drawn from the author's 30 plus years of extensive real world experience are included* Both hardware and software are discussed concerning their roles in power
