High Sensitivity Preamplifier for Quartz Enhanced Photoacoustic Spectroscopy Sensors

Not Accessible

Your library or personal account may give you access

Abstract

A design of QEPAS sensor preamplifier based on the voltage mode amplifier configuration was investigated. Such an implementation results in at least order of magnitude signal gain in comparison to the transimpedance amplifier configurations used previously.
