A system may include first and second node, switch, driver, capacitor, and second driver. The first node may be at first voltage. The second node may be at second voltage. The switch may be coupled to the second node and output of the second driver and configured to receive input at third voltage and voltage at fourth voltage and to provide the input to the second node when the fourth voltage is greater than the third voltage. The driver may be coupled to the first and second nodes and configured to receive driver input and to generate intermediate voltage based on the driver input. The capacitor may be coupled to the driver to shift the intermediate voltage. The second driver may be coupled to the second node and the driver and configured to receive second driver input and the shifted intermediate voltage to generate the voltage at the fourth voltage.
