摘要
研究运算放大器输入信号中干扰信号与有用信号幅度相差较大并使运算放大器输出信号产生截顶时，运算放大器对干扰信号与有用信号放大倍数的变化；分析出现截顶的优缺点．
The difference of amplication between valid signal and interference signal in thesame operational amplifier is pesented in the paper when the amplitude disparities betweenvalid signal and interference signal in the input signal of the operational amplifier is largerand an output signal cutoff peak is produced. Then the advantages and disadvantages of theoutput signal cutoff peak is analysed.
