Power Management in Mobile Devices

Now that mobile has become standard, the consumer not only expects mobility but demands 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 isa large and growing gap between what devices can do and the amount of energy batteries can deliver. In fact, the main limiting factor in many portable device designs is not hardware or software, but instead how much power can be delivered by a battery.This book describes various design approaches to reduce the amount of power a circuit consumes and techniques to effectively manage the available power from a battery.
