Automatic symbolic analysis of SC networks using modified nodal approach

This paper presents symbolic analysis of Switched-Capacitor (SC) circuits in the z-domain using the Modified Nodal Approach (MNA). The analyses are performed on the SymsimC symbolic simulator, which also enables s-domain network analysis. The results of simulations are demonstrated on practical examples of SC-networks. The influence of finite gain and bandwidth of operational amplifiers on the circuit's behaviour is also examined.
