Abstract :
This paper proposes a model to help designers maximize output power in systems that contain a DC energy transducer and a DC-DC multiplier charge pump by identifying initial circuit and device parameter estimates for SPICE simulations. This model also enables designers to use simple equations to estimate the sensitivity of the DC transducer´s characteristic parameters, like short circuit current and output impedance, on the charge pump´s output power.
