Abstract
This circuit uses a simple structure of series-parallel connected capacitors and diodes to implement an n/m voltage divider circuit. There are n columns of series connected capacitors, which columns are all connected in parallel. The capacitor valves are selected so that in each column the ratio of charging capacitance to discharging capacitance is n:m. The diodes automatically switch the capacitor charging and discharging currents to the series-parallel connected capacitors.
