Abstract
A new model, of a dynamic nature, is proposed for the basic analysis of switched capacitor circuits. The model represents a significant conceptual departure from the traditional frequency-dependent equivalent resistor model. Using Filippov's concept of solution for systems governed by right-hand side discontinuous differential equations, such as those regulated by a pulse-width modulation control strategy, a general and more realistic dynamical model is proposed for switched capacitor circuits. The traditional model is easily rederived and reinterpreted as the outcome of a sequential singular perturbation procedure carried on an idealized version of the proposed dynamical model.
