摘要

在这项工作中，我们提出了一种基于低电压(/spl plusmn/0.75 V)低功率(0.7 mW)电流模式的电阻式气体传感器集成接口。提出的接口，其中包括一个接地电阻传感器，显示出补偿非理想的无源和有源元件，特别是电压偏移的能力。灵敏度值设置为约16 mV/K/spl Omega/，而理论分辨率约为135 /spl Omega/，对应于低于1.5 ppm的气体分辨率。

A low-voltage low-power current-mode gas sensor integrated interface

In this work, we present a low-voltage (/spl plusmn/0.75 V) low-power (0.7 mW) current mode-based integrated interface for resistive gas sensors. The proposed interface, which includes a grounded resistive sensor, shows the capability of compensation of non-idealities of passive and active components, in particular the voltage offset. The sensitivity value has been set to about 16 mV/K/spl Omega/, while theoretical resolution is about 135 /spl Omega/, to which corresponds a gas resolution lower than 1.5 ppm.
