Calculation of Negative Feedback Amplifying Circuit and Simulation Based on Multisim12
摘要
Abstract
The calculation of negative feedback amplifying circuit is often used in the circuit design or analysis .Therefore at first the theoretical calculation of negative feedback amplifying circuit was introduced .The general calculation and approximate esti-mation methods were given .Then the common circuit with negative feedback amplification was simulated in Multisim 12.It was con-sidered that the impact of load effect existed in the input and output port of feedback network on basic amplifier .After the analysis and calculation of simulation the waveforms and data , it shows that the relationship between closed loop and opened loop circuit to gain and frequency band is in good agreement with theoretical analysis .关键词
