静态工作点与放大电路性能的关系

Relationship between quiescent point and amplifying circuit performance

以单管共射放大电路为例,讨论放大电路中静态工作点与动态参数、输出波形的关系,得出调整静态工作点和动态参数的可行办法,有利于理解和掌握模拟放大电路的原理与实质。

Taking the single-transistor common-emitter amplifying circuit as an example,the relationship of quiescent opera-ting point in the amplifying circuit with dynamic parameters and output waveform is discussed. The feasible ways of adjusting the quiescent operating point and dynamic parameters were achieved. The research is conducive to understand and master the princi-ple and substance of analog amplifying circuit.
