Abstract
A voltage phase generator that generates a normal voltage phase, a negated normal voltage phase, a boosted voltage phase, and a negated boosted voltage phase. The voltage phase generator includes a first driver circuit that supplies the normal voltage phase to a first output node, and a second driver circuit that supplies the negated normal voltage phase to a second output node. The first and second driver circuits are driven by additional voltage phases that have a boosted voltage. In one preferred embodiment, each of the driver circuits includes a pull-up connected between a supply voltage and one of the output nodes, and a pull-down connected between ground and the one output node. Additionally, the present invention provides a voltage boosting circuit that includes a booster circuit and a voltage phase generator. The booster circuit receives four voltage phases and generates a boosted voltage, and the voltage phase generator generates the four voltage phases and additional voltage phases that have a boosted voltage. The additional voltage phases drive driver circuits that supply the normal voltage phase and the negated normal voltage phase to the booster circuit. In a preferred…
