Charge-pumps consistent with this invention comprise a first transistor for sinking a current from an output node; a second transistor coupled between the first transistor and a ground node, wherein the second transistor interrupts the sinking current when the second transistor is turned off; and a current source to provide a turn-off current to a common node between the first transistor and the second transistor when the second transistor interrupts the sinking current. Charge-pump circuits consistent with this invention comprise a first transistor for sinking a current from an output node; a second transistor coupled between the first transistor and a ground node, wherein the second transistor interrupts the sinking current when the second transistor is turned off; and a clamping circuit to clamp a common node between the first transistor and the second transistor below a clamping voltage.
