Analysis of Influence of Working Environment of Amplification Circuit Based on Q-point Adjustment on Magnification Factor
This paper describes that the more practical partial voltage bias amplifier circuit is taken as an example,the basic circuit is built,and the static operating point and dynamic voltage amplification are measured and analyzed according to the static and dynamic analysis mechanism.Through the analysis of experimental and theoretical data,it can be seen that the static operating point will affect the dynamic range of the amplifier circuit.Under the condition of stable output of the amplifying circuit,the best magnification ratio conforming to the partial voltage bias amplifying circuit is found by changing the working environment of the circuit.
