SNR Improvement of QEPAS System by Preamplifier Circuit Optimization and Frequency Locked Technique

Abstract Preamplifier circuit noise is of great importance in quartz enhanced photoacoustic spectroscopy (QEPAS) system. In this paper, several noise sources are evaluated and discussed in detail. Based on the noise characteristics, the corresponding noise reduction method is proposed. In addition,...
