Abstract
Minimizing the energy consumption of battery-powered 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 operating 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 tracking loop along with the DC-DC converter and test circuitry were fabricated in a 65 nm CMOS process. The area overhead of the control loop is only 0.05 mm2. Measured energy savings of the order of 50%-100% are obtained on tracking the minimum energy point (MEP) as it varies with workload and temperature. The DC-DC converter delivers load voltages as low as 250 mV and achieved an efficiency >80% while delivering load powers of the order of 1 muW and higher from a 1.2 V supply.
