Abstract
Systems and methods described herein correspond to supply harvesting operations. Power management circuitry may receive a supply voltage from other power management circuitry. This supply voltage may be a harvested supply from the other power management circuitry. Moreover, some of the power management circuitry may be operated as controller power management circuitry to supply the supply voltage via one or more rails and some of the power management circuitry may be operated as leaf power management circuitry to harvest the supply voltage from the one or more rails. Leaf power management circuitry may exclude a regulator, enabling that leaf power management circuitry to be entered into a lower power mode than previously enabled when the regulator was included.
