Abstract

Minimizing the energy consumption of battery-pow- ered systems is a key focus in integrated circuit design. This paper presents an energy minimization loop, with on-chip energy sensor circuitry, that can dynamically track the minimum energy oper- ating voltage of arbitrary digital circuits with changing workload and operating conditions. An embedded DC–DC converter which enables this minimum energy operation is designed to deliver load voltages between 0.25 V to 0.7 V. The minimum energy trackin
