| 中文摘要: |
| 积分电路主要用于波形变换、放大电路失调电压的消除及反馈控制中的积分补偿等场合,是模拟电路教学中的重要内容。本文在频域范围内经过推导,证明在基本积分电路的基础上引入反馈电阻RF可以限制电路的低频增益,减少失调电压带来的积分漂移。并基于multisim仿真平台上验证这一结论,最后给出了反馈电阻、反馈电容的参数设计方法,可供模拟电子电路设计人员参考。 |
| 英文摘要: |
| The integrated Circuit is mainly used for waveform transformation, elimination of voltage imbalance of amplifier circuit and integral compensation in feedback control. It is an important content in analog circuit teaching. In the frequency domain, it is proved that the introduction of feedback resistor RFon the basis of the basic integrated circuit can limit the low frequency gain of the circuit and reduce the integral drift caused by the maladjusted voltage. Finally, the parameter design method of feedback resistor and feedback capacitor is given, which can be used for reference by circuit designer and analog electronic experiment technician. |
