AbstractThis paper presents a dynamic model for on-chip inverting capacitive charge pumps driven by two non-overlapping clock signals implementing the charge reusing technique to mitigate the efficiency loss due to the charge and discharge process of the parasitic capacitances during the falling edge of one clock signal and the rising edge of the other. The model is validated with both circuit-level simulations and experimental results showing high accuracy. An application example in micro energy harvesting is shown.
