        Abstract:        Reports a method of design 2nth-order Voltage-controlled Voltage Source(VCVS) low-pass filter, based on analyzing the error isogram by MathCAD, the paper put forward the optimal design plan of 2nth-order VCVS unit-gain Butterworth f0 Hz low-pass filter: firstly, decompose 2nth-order filter into n 2nd-order filters. For the ith one, if monomial coefficient of the polynomial expression is αi, select two capacitances C1i and C2i, making C2i/C1i 0.25αi2, and then calculate value of the two resistances by the same expression 1/παi f0 C1i. Obviously, the design plan has the advantages of convenience, low-cost. And with the aid of Monte Carlo analysis, parameter sweep analysis and real circuit experiment the design plan has also been verified its advantage of stability. In addition, analysises also shows different C, R have different influence on the filter features.
