Abstract :
Dynamically adjusting supply voltage based on processing load in applications that involve variable workloads to reduce energy consumption has been proposed. A similar idea for tracking temperature and process variations using a dynamic switching regulator has also been proposed. In this paper a buck-converter switching regulator chip for use in an energy-on-demand system is shown.
