| Abstract: | Introducing negative feedback into amplifying circuit can effectively improve the circuit performance. Through Multisim2001 software, the article introduces the static and dynamic simulation operation of negative feedback amplifying circuit, analyzes the reasons of the distortion of the output voltage, and expounds the principle of performance improvement. For the best performance for the circuit, through comparing, analyzing feedback element on the feedback of different parameters, the article verifies in the linear amplifier circuit in low frequency, only introduce appropriate quantity feedback can make circuits obtain ideal effect. |
