本文提出一种新的具有较好热稳定性的气敏元件结构。在这种结构里,气敏元件的输出无需外接取样电阻即可获得。文中对现有气敏元件和新型结构气敏元件的热稳定性作了理论分析和实验对比。本设计也适用于其它类型半导体气敏元件。
In this paper, a new gas sensor with better thermal stability is proposed. In this structure, the gas sensor output without external sampling resistance can be obtained. In this paper, the theoretical analysis and experimental comparison of the thermal stability of the existing gas sensors and the new structural gas sensors are made. This design also applies to other types of semiconductor gas sensors.
