Abstract

An apparatus comprises a power source connected to a buffer capacitor. The apparatus comprises a first switch connected between the buffer capacitor and a driven switch. The buffer capacitor is charged by the power source when the first switch is turned off. The apparatus comprises a comparator. The comparator monitors the charging of the buffer capacitor. In response to the buffer capacitor reaching a threshold amount of charge, the comparator turns on the first switch to initiate a charge redistribution of charge from the buffer capacitor to the driven switch.
