1. A voltage level translator circuit, comprising:

  • a digital logic circuit having a digital logic signal;

    first and second high voltage capacitors, each having a first and second connection, wherein the second capacitor has the first connection has an electrical coupling to the digital logic signal and the electrical coupling includes logic inversion;

    a cross-coupled inverter pair having the output of at least one inverter of the pair electrically coupled to the other connection of the at least one high-voltage capacitor, wherein the second capacitor has the second connection electrically coupled to an output of the other of the at least one inverter of the pair; and

    a sensing circuit configured to sense the state of the cross-coupled inverter pair and to produce an output signal having a voltage level higher than the digital logic signal.
