A Novel State-Space Synthesis Method for Designing Low-Sensitivity Switched Capacitor Filters

本文提出了一种新的实现低灵敏度SCF的状态空间法。导出了具有低灵敏度性质的SCF的状态空间方程矩阵集的一般形式及该矩阵集与电压传递函数间的关系。结果表明,用该方法设计具有低灵敏度特性的开关电容滤波器,非常简便。

This paper presents a novel state-space synthesis method for designing switched capacitor filters (SCFs) which (how the low-sensitivity to component variations in the passband. A general form of the matrix set of the state-space equations for SCFs with low-sensitivity performance and the relationship between the matrix set and the voltage transfer function are given. The results show that it is very simple to design low-sensitivity SCFs by the method presented.
