| 摘 要： | 用理想运放模型设计的有源微分电路的不足表现为，幅频特性有远离微分规律的尖峰，符合微分规律的频带不宽。为此提出在有源微分电路的传递函数中计及实际运放幅频特性，增加与输入电容串联的电阻，可使有源微分电路的幅频特性没有不符合微分规律的尖峰，符合微分规律的频带达到最宽。

| Abstract: | By ideal operation amplifier (op-amp) model, the frequency response of differentiator is with a large peak away from differential rule, and the band keeping with differential rule is not wide. By using real open loop frequency response of op-amp in differentiator transfer function and placing a resistor in series with the input capacitor, the frequency response of the differentiator is with no peak away from differential rule, and the band keeping with differential rule could be the widest. |
