Abstract
This paper presents a power management unit (PMU) driving a microcontroller, and controlling a power knob that enables adaptation to the sensed power availability over an ultra-wide range, well beyond voltage scaling. Conventional battery-powered operation is augmented with pure harvesting. Wide power adaptation is enabled by comparator delay self-biasing and zero-current switching scheme shared among all power modes with single-cycle convergence.
