Abstract
A system and method to provide a slow start up voltage, such as that can slowly ramp up or down by cyclically coupling a pair of associated energy storage devices, such as capacitors, during a start-up phase. The cyclic coupling of the capacitors, in conjunction with causing a change in charge associated with a first of the storage devices, results in incremental changes in the energy of the second energy storage device over a plurality of cycles. The energy associated with the second storage device can be used to control output circuitry that provides a desired ramp output signal.
