这是一种设计双二阶SCF电路的新方法:利用配方构造电路,可直接决定元件参数,简单直观,物理概念清楚,便于CAD。电路仍保留了对寄生电容不敏感的特性,可适用于各种类型的双二阶SCF电路的设计。
This is a new way to design a double second-order SCF circuit. By using the formula to construct the circuit, the parameters of the device can be determined directly, which is simple and intuitive. The physical concept is clear and convenient for CAD. Circuit still retains the parasitic capacitance is not sensitive to the characteristics of various types of second-order SCF circuit can be applied to the design.
