摘要
以电流源供电的电桥测温电路系统为对象,对具有模拟电路和数字电路混合形式的测量系统,采用系统分析的方法,导出了测量系统特性的重要参数电-热转换灵敏度,讨论了提高系统测量灵敏度的途径。
In the research of the bridge temperature measure system supplied by constant current source, system analizing method was used to deduct the important parameter of electro-thermal converting Sensitivity of this system, which is mixed with both analog circuit and digital circuit, and the ways to enhance the sensitivity was presented.
