Abstract
Two storage capacitors connected in parallel with a constant current source in a charging mode and connected in series in a second mode to increase output voltage. A comparator senses the amplitude of the output voltage and controls the current supplied to the capacitors in the charging mode to increase or decrease the output voltage to coincide with a predetermined amplitude.
