它的输入级中,反相与非反相输入端之间有一个单位增益缓冲器(unity-gain buffer),可以为 CFA 结构带来一些特有的优点。CFA 受欢迎的程度一直没有像电压回馈设计这么高,直到全互补双极制程的出现。

The unity gain buffer will be good for designing high frequency SCF if its resistive effect can be eliminated and then the overall parasitic sensitivity will be greatly lowered.
用单位增益缓冲器构成的开关电容滤波器(SCF),若能消除寄生电容引起的“阻性”寄生,则可用于高频设计,总寄生灵敏度会因此大大降低。
