WEIGHTED VOLTAGE-CAPACITOR CLUSTERS WITH CLOUD-CHARGING FOR ULTRA-FAST VOLTAGE SCALING WITH NO CHARGE REDISTRIBUTION LOSS

摘要

An on-chip power management system includes one or more processing cores and one or more switched capacitor voltage regulators, each supplying power at an output voltage to one of the cores. One or more flying capacitors supply the power at a supply voltage to each of the switched capacitor voltage regulators. A flying capacitor controller allocates each of the flying capacitors to the switched capacitor voltage regulators.
