按双线性变换方法构成的一阶及二阶开关电容电路不但可以用来构成所有各种类型的级联滤波器
而且在按照模拟低通原型滤波器构成的跳耦电路中
用适当的二阶开关电容电路代替积分电路
可将原型滤波器变换为带通或带阻滤波器。文中给出了一阶及二阶开关电容电路的系统设计方法
讨论了各类电路的灵敏度及如何调整电路参数以获得最大输出动态范围。
Switched-capacitor one-order and two-order sections may be used in various types of cascade filters. A leap-frog low-pass filter may be transformed into a band-pass or band-stop filter
if the integrators in the prototype filter are replaced by the corresponding switched-capacitor two-order sections. This paper presents a systematic design method for switched-capacitor one-order and two-order sections using bilinear transformation. In order to maximize the output dynamic range
the optimal circuit parameters are selected. The computation and comparison of the sensitivities for the two-order sections are discussed in detail.
