20100308899 | Dual-Output Triple-Vdd Charge Pump - A dual-output triple-Vdd charge pump as two pumped outputs that are both pumped to three times the power-supply voltage, 3×Vdd. This pumped output voltage is reduced by two p-channel inner diode drops, to 3×Vdd−2×|Vtp|. A pair of cross-coupled n-channel transistors alternately charge two inner nodes from the power supply. Inner pumping capacitors drive inner nodes between Vdd and 2×Vdd, and the cross-coupling of the gates turns off one of the cross-coupled n-channel transistors when its inner node is being driven high.

The outer node is also pumped by an outer pumping capacitor that drives the outer node between 2×Vdd−|Vtp| and 3×Vdd−|Vtp|. A p-channel outer diode transistor conducts from the outer node to the pumped output node, causing another |Vtp| voltage drop.
