本文提出和讨论了开关电容网络(SCN)的“Z域链电容”概念、并讨论了如何将它应用于SCN的节点分析。文中还给出了直接列出节点电荷方程增广矩阵[Y_n-Q_n]的方法。 本文所述的方法比较简便、且适用于输入为任意的情形。文中给出了计算机辅助分析(CAA)框图和计算实例,所得结果和其他文献的分析结果能很好地吻合。 This paper presents and discusses the concept of “Z-domain chain capacitor” in switched capacitor network (SCN) and discusses how to apply it to node analysis in SCN. The paper also gives a direct method to list the node charge equation augmentation matrix [Y_n-Q_n]. The method described in this article is relatively simple and suitable for any input situation. The paper gives a computer aided analysis (CAA) block diagram and calculation examples, the results obtained and other documents of the analysis results can be well matched.
