The preamplifier circuit noise analysis and design applied in quartz tuning fork photo-acoustic spectroscopy

摘要：

　　The noise of the preamplifier circuit in quartz tuning fork photo-acoustic spectroscopy is analyzed, and every noise source is evaluated and validated in detail.Based on the noise characteristic, the corresponding noise reduction method is proposed.Moreover, the optimal parameter of the circuit system is described, including the ohm range of the cross resistance, the parameters of the operational amplifier and the design of circuit structure.At last, the argument whether the output voltage amplification is needed is conducted.
