中文摘要：

利用MathCAD绘制单位增益压控电压源二阶巴特沃斯高通滤波器参数方程的误差等值曲线,对其分析研究后得出一种优化设计方案,即首先挑选电容,使C1=C2;然后利用公式计算电阻值。显然,这种设计方案具有方便、低成本,易于补偿温漂的优势。经Multisim-10仿真分析,还证实了该方案具有最稳定性的特点。

英文摘要：

Using MathCAD to draw the error isogram of Voltage-controlled VoltageSource（VCVS） 2nd-order high-pass filter＇s parametric equation,after analysis and research,the paper puts forward an optimized design scheme： firstly,selecting two capacitances C1 and C2,making C1= C2;and then calculating the value of two resistances.Obviously,this design scheme has the advantages of convenience,low-cost and easy compensation of temperature drift.And the Multisim-10 simulation also verified its advantage of the most stable.
