开关电容电路计算机辅助分析的一种有效方法

本文提出了一种开关电容也路计算机辅助分析的有效方法,此法对电路的拓扑结构、开关的相,以及占空度没有任何限制。本方法首先形成SC电路的改进节点方程,然后通过几个简单的步骤将其转换成SC电路的状态方程,最后,由一个精确解公式可以很容易地获得SC电路的传递函数。按本计算法编制了一个程序,在DJS—6计算机上计算了两个例题,计算结果和参考文献中的结果完全吻合。

An Efficient Approach to the Computer-Aided Analysis of Switched Capacitor Circuits

An efficient approach to the compute aided analysis of switched capacitor circuits has been presented, No topological, phase and duty cycle constraints have been imposed on the circuits, According to this method a modified nodal equation of SC circuits has first been formed and then transformed to a state equation of SC circuits through several simple steps, Finally, using an exact formulation, th transfer function of SC circuits can be obtained easily, The method has been implemented as FORTRAN program and two examples fnr SC circuits have been comp uted on the DIS-6 digital computer, The computed results have been shown to coincide with those provided by references.
