用移源法对差放输入等效电路的解析

A NEW MOTHOD OF ANALYSE THE EQUIVALENT CIRCUIT IN DIFFERENTIAL AMPLIFIERS INPUT

应用移源法及替代定理，将差放输入等效电路中的单端输入和双端输入模型化一，强调了差值电流的作用。

From the mothod of the moving source and the law of replacing,the type of the equal circuit in signle or double input terminal is unified. And also,emphasizing the important concept in differ value current. That is very small.A new type analyse mothod is provided.
