Analysis of Switched Capacitor Circuits Based on Unified Ideal Switch Model

The paper proposes a unified and efficient switch model for analysis of switched capacitor circuits. The switch model depends on ideal switch concept. The model is unique and valid for all states of switches. The developed model is based on modified nodal analysis (MNA). The analysis with the new switch model requires only one topology and uses uniform system equations regardless of states of switches. As an application of switched capacitors, the simulation of an integrator circuit is performed. Simulation results show the accuracy of the approach.
