摘要

In this article, a battery-indifferent microcontroller unit (MCU) with wide power–performance scaling is presented to enable continuous operation with a sub-mm2 on-chip solar cell, even when the battery runs out of energy. The MCU is based on dual-mode standard cells to extend power–performance flexibility well beyond allowed by voltage-scaled CMOS logic. Ripple power gating is introduced to allow...
