摘要
以电压串联负反馈为例,采用晶体管的广义h参数,对反馈网络的负载效应做了定量分析。得到负反馈放大器放大倍数一般表达式的使用条件,同时强调了反馈系数与信号源内阻及负载电阻无关。
Taking the negative feedback with voltage series as an example, the load effect of feedback network is analyzed quantitatively by employing the generalized h parameter of transistor. The application conditions of general expression for the amplified multiple of negative feedback amplifier are obtained, and meanwhile emphasizing that the feedback coefficient has nothing to do with the inner resistance of signal source and load resistance.
