摘要
为形象掌握电子技术中多级放大电路静态、动态特性,采用Multisim仿真平台、实验测试的方法,研究了负反馈放大电路与基本放大电路的电压放大倍数、输入、输出电阻、频带宽度等动态参数变化特点。负反馈放大电路以牺牲放大倍数换取性能的稳定,扩展了频带。仿真平台与实验测试相结合,强化了分析问题能力和实际电路设计,值得推广和应用。
Image master electronic technology in multistage amplifier circuit, and the dynamic and static characteristics,using Multisim Simulation Platform,test method of negative feedback amplifying circuit and basic amplifying circuit of voltage amplification ratio,input and output resistance and the band width dynamic parameters change characteristics.Negative feedback amplification circuit in exchange for the stability of the performance of the amplification factor,the expansion of the frequency band.The combination of simulation platform and experimental test,strengthen the ability of analysis and practical circuit design,it is worth popularizing and applying.
