Abstract :
This paper presents an approach for the description and analysis of periodically switched linear circuits, with emphasis on switched-capacitor and switched-current filters, using state-variable methods. The implementation of the algorithm in a computer program is described, and an interesting method for treating the final conditions to initial conditions conversion problem that arises in this kind of analysis is presented.
