Abstract :
This paper presents a z-domain model for voltage-doubler charge pumps that considers the variations of both input voltage and load current. We show how the model can be used to design an efficient control system for a typical charge pump. The application of the model is demonstrated through circuit simulations of a regulated charge pump, designed to keep area and energy consumption low.
