三阶压控电压源低通滤波器稳定性的分析

Analysis of the stability of voltage-controlled voltage source low-pass filter 3

利用罗斯准则，证明了三阶压控电压源低通滤波器稳定工作条件是Ａup＜２．７５，并进行了ＥＷＢ仿真。

Applying Routh criterion, the stable operating Condition of voltage - controlled voltage source filter 3 is'proved,which is the voltage amplification ratio that is smaller than 2. 75. The result is simulated by the EWB software.
