摘要

这封信提供了一种新的集成型线性化数字化热敏电阻(ILD)。提出的ILD,在其基本形式中,采用增强型集成型数字化仪,配备一对线性化电阻。它基于一种新颖的三相方法,并提供线性直接数字温度指示。该方案采用简单的结构,并且不需要在以前的热敏电阻前端需要的特殊部件,如匹配参考和对数放大器。这封信中还讨论了为更短和更长的操作跨度量身定制的两种ILD变体。通过仿真和详细的实验研究,对所提方案的性能进行了分析和提出。结果显示,ILD(及其变体)的能力,作为一个精确的线性化数字前端在大跨度。

An Efficient Multiphase Integration-Type Linear Digital Thermistor Front-End
This letter proffers a new integrating-type linearizing digitizer (ILD) for thermistors. The proposed ILD, in its basic form, employs an enhanced integrating-type digitizer, equipped with a couple of linearizing resistors. It works based on a novel triple-phase methodology and renders a linear direct-digital indication of temperature. The schemes use a simple architecture and do not require special parts, such as matched references and logarithmic amplifier, which are needed in prior thermistor-front-ends. Two variants of ILD, which are tailored for shorter and longer operational spans, are also discussed in this letter. The performance of the proposed schemes is analyzed and brought-forth using simulation and detailed experimental studies. Results showcase the ability of ILD (and its variant) to act as an accurate linearizing digital front-end over wide span.
