摘要

本文介绍了一种基于CMOS 65nm技术节点设计的智能温度传感器的架构，用于物联网和RFID应用。将微调电路和部分读出操作转移到数字域，再加上传感器模拟前端的设计复杂性降低，可以最大限度地降低功耗。在[−40°C÷125°C]温度范围内，通过两点校准获得的传感器最大误差为±0.3°C，在转换速度为1 Sa/s的情况下，平均功耗为375 nW。

A low power temperature sensor for IOT applications in CMOS 65nm technology

This paper describes the architecture of a smart temperature sensor designed in CMOS 65nm technology node, intended for IOT and RFID applications. The shift of the trimming circuitry and of a portion of the readout operations into the digital domain, combined with a reduced design complexity in the sensor analog front-end, allow the minimization of the power consumption. The maximum inaccuracy of the sensor, obtained by means of a two point calibration, is ±0.3°C over the [−40°C÷125°C] temperature range, with an average power consumption of 375 nW at a conversion speed of 1 Sa/s.
