摘　　要：总结了目前常见的放大器零点漂移的处理方法 ,分析了各自的原理 ,提出了一种基于智能仪表的自动调零方法。讨论了该方法调节的机理、存在的效应、实现的方法和步骤。Self-zero is a very common technique,It is used in amplifier where zero-drift occur frequently.Today,the methods of Self-zero are sort into 2,one is realized by the software of single-computer,and another is acted by self-adjust technique.Now the third method is discussed in the paper.the theory and the application of the method are also given.

关 键 词：放大器 自调零 阶梯效应 智能仪表 零点漂移 信号处理
