Abstract
Official abstract text for this publication.
In one embodiment, an apparatus includes a first supply voltage and a second supply voltage. Level shifter circuitry is configured as a first voltage battery to shift a first voltage and a second voltage battery to shift a second voltage. A first circuit receives the shifted first voltage and sets a third voltage, and receives the shifted second voltage and sets a fourth voltage. The shifted first voltage is greater than the first supply voltage and the shifted second voltage level is less than the second supply voltage. A second circuit sets a fifth voltage and a sixth voltage. The fifth voltage follows the third voltage and the sixth voltage following the fourth voltage.
