Coupling p+n Field-Effect Transistor Circuits for Low Concentration Methane Gas Detection

Coupling p+n Field-Effect Transistor Circuits for Low Concentration Methane Gas Detection

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 (RL), the response to methane of the commercial MP-...
