| Abstract: | In order to make the complex circuit analysis vivid and authentic,a simulation analysis of the negative feedback amplifier circuit performance indicator is proposed based on Multisim 10.The results show that the use of Multisim 10 simulation platform,when the negative feedback is introduced into the amplifier circuit,though it has a lower magnification,can improve the performance of other amplifiers.That is to say,it can increase the input resistance,reduce the output resistance,extend the band amplifier circuit,enhance the frequency characteristics and suppress the non-linear distortion.Compared with traditional analysis methods,it has not only less time and less cost but also a high efficiency. |
