Abstract: In this paper, the relationship between typical circuit structures of gas sensorcircuits and their output noise is analyzed. By using averaged segmenting periodical graphand improved histogram estimation methods, we estimated their noise power spectra andoptimal probability distribution functions (pdf). The results were confirmed throughexperiment studies.
Keywords: gas sensor; circuit; noise; power spectrum; probability distribution function.
