负反馈放大器在电子电路中有着极为广泛的应用,采用负反馈技术是改善放大器性能指标的有效手段,放大电路中引入负反馈以后,除放大电路的增益有所下降之外,可以稳定静态工作点和放大倍数,减少非线性失真,扩展频带以及改变输入、输出阻抗,从而改善放大器的性能负反馈在放大电路中广泛应用,它对电路的性能指标有较大的影响。采用Multisim2001电路设计仿真软件进行仿真实验可直观地得出结果,在探讨发展性教育的今天,利用电路仿真技术的先进教学手段进行教学,提高学生学习兴趣和课堂教学效果。
Negative feedback amplifier has a very wide range of applications in electronic circuits, the use of negative feedback technology is an effective means to improve the performance of the amplifier, the introduction of negative feedback in the amplifier circuit, in addition to the amplification gain of the circuit has declined, you can stabilize the static operating point And amplification, reduce nonlinear distortion, extend the band and change the input and output impedance, thereby improving the performance of the amplifier Negative feedback is widely used in the amplifier circuit, which has a greater impact on the performance of the circuit. Multisim2001 circuit design simulation software simulation experiment can intuitively come to the conclusion that in the development of education today, the use of circuit simulation technology advanced teaching methods of teaching, improve student interest in learning and classroom teaching.
