Ultra-low-voltage (ULV) temperature sensors are essential to pursue continuous temperature logging by self-powered Internet-of-Things (IoT) nodes. The widespread applications range from environmental temperature monitoring to electrical machine status detection and IC thermal protection [1–6]. Designing such temperature sensors compatible with a sub-0.5 V supply (VDD) can suit the common energy-harvesting units (e.g., solar cells), simplifying the power-management unit and the final deployment [1]. Also, to be harmonious with the mainstream deep-submicron processes for IoT system-on-chip, it is desirable to develop ULV temperature sensors suitable for those technology nodes.

摘要

Ultra-low-voltage (ULV) temperature sensors are essential to pursue continuous temperature logging by self-powered Internet-of-Things (IoT) nodes. The widespread applications range from environmental temperature monitoring to electrical machine status detection and IC thermal protection [1–6]. Designing such temperature sensors compatible with a sub-0.5 V supply (VDD) can suit the common energy-harvesting units (e.g., solar cells), simplifying the power-management unit and the final deployment [1]. Also, to be harmonious with the mainstream deep-submicron processes for IoT system-on-chip, it is desirable to develop ULV temperature sensors suitable for those technology nodes.
