基于直流换向方法的电阻测量技术

随着现代制造业的飞速发展,电子元器件的体积将变得越来越小,于是测试功率受到了很大的限制,都需要降低测试电流,这就对系统测试小电压信号时的噪声抑制能力提出了极大的挑战,本文在经典偏置补偿测量电阻方法的基础上,介绍了基于直流电流换向方法的电阻测量技术,并对这两种方法进行了比较,得出基于直流电流换向方法在抑制噪声能力上的优越性。

Resistant Measurement Based on DC Reversals

Size of the electronic competent is becoming more and more small while the modern manufacturing industry is developing at high speed,testing consuming is restricted and current have to be decreased,which challenge the system's noise rejection ability when testing low level voltage,on the base of classic offset compensation,this article introduces a resistant detecting method based on DC current reversals and compare them with each other,finally indicating the the former's superior performance in noise rejec...
