【Abstract】 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.更多还原
