摘要

提出了一种多用途、低功耗和节能的物联网(IoT)电容-数字转换器(CDC),该转换器基于具有自适应速度、分辨率和范围的全动态架构。支持从1S/s到100kS/s的采样率,可以数字化1.23至24.59pF的电容,而功率固有范围为0.1nW至1 μ W。这使得设计通用性强,可以有效地处理不同速度要求和不同电容值的各种传感器。0.1nW的最低绝对功率比现有技术小20倍以上,从18到59fJ/ v-step的性能因数(FoM)也是现有设计中最低的。例如,通过连接MEMS压力传感器,该芯片可以以仅0.8nW的速度以100秒/秒的速度测量环境压力。

A 0.1nW −1µW All-Dynamic Capacitance-to-Digital Converter with Power/Speed/Capacitance Scalability
A versatile, low power and energy efficient Capacitance-to-Digital Converter (CDC) for Internet-of-Things (IoT) is presented, based on an all-dynamic architecture with adaptable speed, resolution and range. Sampling rates from 1S/s up to 100kS/s are supported and capacitances from 1.23 to 24.59pF can be digitized while the power scales inherently from 0.1nW to 1µW. This makes the design versatile to efficiently deal with a variety of sensors with different speed requirements and different capacitance values. The 0.1nW lowest absolute power is >20x smaller than prior-art, and the Figure-of-Merit (FoM) from 18 to 59fJ/conv-step is also the lowest among prior designs. As example, by connecting a MEMS pressure sensor, this chip can measure environmental pressure with only 0.8nW at a speed of 100S/s.
