摘要

我们提出了一种采用独特差分设计的电解质-绝缘体-半导体电容器（EISCAP）传感器，其中使用了无液参考（LR）器件作为参考信号源。在基于交流激励调整的输出匹配之后，LR 器件可为差分式 EISCAP 传感器提供高达 80% 的背景信号消除效率。pH 检测实验结果表明，与传统 EISCAP 传感器相比，差分 EISCAP 传感器具有更高的精度和时间稳定性。差分设计为 EISCAP 传感器在监测领域的应用提供了一个可行的优化方向。

Optimization of electrolyte-insulator-semiconductor capacitor sensor by differential design

An electrolyte-insulator-semiconductor capacitor (EISCAP) sensor with the unique differential design is proposed where a liquid-free reference (LR) device is used as the reference signal source. After the output matching based on AC excitation adjustment, LR device can provide up to 80% elimination efficiency of background signal for differential EISCAP sensor. Experiment results of pH sensing demonstrate that the differential EISCAP sensor has the better accuracy and time stability compared with conventional EISCAP sensor. The differential design provides a feasible optimization direction for EISCAP sensor in monitoring applications.
