Cross-coupled charge-pumps. At least some of the example embodiment are methods including: pumping charge from a first capacitor through a first field effect transistor (FET) to a voltage output and from a second capacitor through a second FET to the voltage output of the charge pump; refreshing charge to a third capacitor and a fourth capacitor during the pumping of charge; electrically isolating the first through fourth capacitors during a dead time; and then pumping charge from the third capacitor through a third FET to the voltage output and from the fourth capacitor through a fourth FET to the voltage output of the charge pump; and refreshing charge to the first capacitor and the second capacitor during the pumping of charge from the third and fourth capacitors.
