一种便携SAW气体传感器的电路设计
资料介绍
该文采用信号处理技术，设计了一种振荡电路。该电路解决了双延迟线型声表面波（SAW）器件不易起振，频率跳变等问题。整个电路结构简单，对插损低于20dB的器件有很好的起振效果，满足气体检测的需要。
An oscillation circuit for dual delay lines type of SAW devices has been designed in this paper. The signal processing technology has been used to avoid the uneasy-oscillation and the frequency-hopping of the dual delay line SAW device. The proposed circuit has the features of simple structure and easy-oscillation for the device having the insertion loss of below 20 dB,and can satisfy the demands for the vapor detection.
