ABSTRACT
Integrated circuit (IC) power consumption has become a significant issue for most applications. For wireless and battery-powered applications, the key issue is that of maximizing battery life. This issue is exacerbated by the continuously increasing amounts of computing required for advanced functionality, such as color displays and full-motion video. For tethered applications, where batteries do not limit the power budgets, power is also an issue because it directly affects critical manufacturing parameters, such as die size, packaging choices, and unit cost.
