摘要

本文介绍了一个驱动微控制器的电源管理单元(PMU)，并控制一个功率旋钮，使其能够在超宽范围内适应感应功率可用性，远远超出电压缩放。传统的电池供电操作增加了纯粹的收获。通过比较器延迟自偏置和所有功率模式共享的零电流开关方案，实现了单周期收敛的宽功率自适应。

Integrated Power Management and Microcontroller for Ultra-Wide Power Adaptation down to nW

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.
