This work presents a fully-integrated switched-capacitor dc-dc design with a centralized dual-lower-bound hysteresis controller for emerging Internet-of-Things applications. A fully-integrated centralized dual-lower-bound hysteresis controller with compensation techniques is proposed and implemented in 180-nm technology to achieve an enhanced power density by applying delay compensations to the dual-lower-bound hysteresis controller. The frequency control with pattern detection maximizes the intrinsic transient speed to one clock cycle on average. An over 1000x load-current range with > 65% efficiency is achieved by measurement.
