本文介绍在具有电压反向开关(VIS)的开关电容(SC)滤波器中,电感模拟电路的新设计方法。浮地电感和浮地VIS能同时实现。该电路对于底片寄生电容很不敏感,并且完全保持了VIS-SC滤波器所特有的良好敏感性。作为例子,本文给出了一个具有浮地电感的5阶椭圆低通滤波器,实验结果与理论相符。 This article describes a new design methodology for inductive analog circuits in a switched capacitor (SC) filter with voltage reverse switching (VIS). Floating inductance and floating VIS can be achieved at the same time. This circuit is insensitive to the negative parasitic capacitance of the negative and fully retains the good sensitivity unique to VIS-SC filters. As an example, a five-order elliptic low-pass filter with floating inductance is given in this paper. The experimental results agree with the theory.
