微分电路R、C参数分析

Analysis on R. C Parameters of a Deffential Circuit

推导了有源微分电路Ｒ、Ｃ参数与信号频率ｆ和运算放大器的电压放大倍数Ａｕ之间的约束关系；并通过一个实际电路说明了微分电路的Ｒ、Ｃ元件的取值准则。

The constraint relationship between R . C parameters of active differential circuit, and inputsignal frequency and the voltage amplification of operational amplifier is derived.An example whichdemonstrates R 1 C parameters of the differential circuit not to be arbitrary is given.
