| 英文摘要 | Nowadays, the detection of low concentration combustible methane gas has attracted great concern. In this paper, a coupling p+n field effect transistor (FET) amplification circuit is designed to detect methane gas. By optimizing the load resistance (R-L), the response to methane of the commercial MP-4 sensor can be magnified similar to 15 times using this coupling circuit. At the same time, it decreases the limit of detection (LOD) from several hundred ppm to similar to 10 ppm methane, with the apparent response of 7.0 +/- 0.2 and voltage signal of 1.1 +/- 0.1 V. This is promising for the detection of trace concentrations of methane gas to avoid an accidental explosion because its lower explosion limit (LEL) is similar to 5%. The mechanism of this coupling circuit is that the n-type FET firstly generates an output voltage (V-OUT) amplification process caused by the gate voltage-induced resistance change of the FET. Then, the p-type FET continues to amplify the signal based on the previous V-OUT amplification process. |
