Abstract
This article presents a power management unit
(PMU) enabling ultra-wide power-performance tradeoff well
beyond voltage scaling, and adaptation to the sensed power/
energy availability in the harvester and battery. Gap-less power
scaling by more than five orders of magnitude and down to
nW permits continuous microcontroller unit (MCU) operation
regardless of the battery energy availability, thanks to a sub-mm

on-chip harvester. Such battery-indifferent operation allows to
considerably shrink the
