Parameters extraction technique for optimal network functions of SC circuits

The parameter extraction technique for symbolic analysis of switched capacitors circuits have been presented. The proposed extraction formulae reduce of cancellation sum-of-product terms amount in transfer function expression. For equivalent circuits of SC the models based on voltage controlled current sources with capacities parameters have been used to avoid the cancellations appearance at the circuit level. The proposed technique is implemented in symbolic circuit analysis program Cirsym. Illustrative examples on SC circuit symbolic analysis are given.
