The results indicate: 1 closed- loop gain and open-loop gain to meet basic relationship; 2 the stability of feedback is enhanced and output resistance increased. Furthermore, the result of open-loop and closed-loop gain of theoretical calculation is consistent with simulation which is applied by EWB software, which confirmed elementary conclusions and relationships in negative-feedback amplifier quantitatively.

结果表明：闭环增益与开环增益满足基本关系式；引入负反馈后稳定性得以提高，输出电阻增大；同时使用EWB对开环与闭环增益也进行了仿真分析，结果与理论计算一致，从而定量地验证了负反馈放大电路中的结论与关系。
