Abstract: The present invention relates to an inverter for high voltage full swing output, for generating an inverter output changing into full swing corresponding to a supply voltage of a high voltage circuit which is m (integer) times higher than a supply voltage of a low voltage circuit, the inverter including a switching circuit having 2 m transistors stacked one upon another, a feedback control circuit supplying gates of the 2 m transistors of the switching circuit with a bias voltage by reducing a full swing inverter output voltage, and a shield voltage source generating a shield voltage to control transmission of the bias voltage.
