Abstract
Methods of operating a charge pump, and charge pumps configured to perform similar methods, involve monitoring a level of a supply voltage of the charge pump, and turning off an oscillator of the charge pump responsive to the level of the supply voltage dropping below a certain level, wherein turning off the oscillator comprises setting an inverter in a ring oscillator loop of the oscillator to a steady state output.
