Ahmed Emira, et al., "50V All-PMOS Charge Pumps Using Low-Voltage Capacitors" IEEE Transactions on Industrial Electronics 60, (10), 2013, 4683. Abstract: In this paper, two high-voltage charge pumps (CPs) are introduced. In order to minimize the area of the pumping capacitors, which dominates the overall area of the CP, high-density capacitors have been utilized. Nonetheless, these high-density capacitors suffer from low breakdown voltage, which is not compatible with the targeted high-voltage application. To circumvent the breakdown limitation, a special clocking scheme is used to limit the
