Abstract

A sensor node with system power tuning is presented for 5-order-of-magnitude adaptation to harvested power. Coordinated tuning of unified voltage/capacitive/light sensor interface, MCU and direct MPPT with no intermediate power conversion scales system power to 3.1nW at 0.3V. Operation at 1lux (moonlight) with 4.1×4.1mm2 light harvester is shown.

具有5个数量级系统功率自适应低至3.1nW且在月光采集下持续运行的多传感器平台

提出了一种具有系统功率调谐的传感器节点，对采集功率进行5个数量级的自适应。统一电压/电容/光传感器接口、MCU和直接MPPT协调调谐，无需中间功率转换，将系统功率在0.3V下达到3.1nW。在1勒克斯(月光)下使用4.1×4.1mm2光采集器进行操作。
