Abstract
An apparatus and method for generating an elevated output voltage. The apparatus includes first and second boot nodes at which a respective elevated voltage is generated, first and second gate nodes, and an output node at which the elevated output voltage is provided. The apparatus further includes first and second switches, each having a gate terminal coupled to a respective gate node. The first switch couples the first boot node to the output node during a first portion of a first phase and the second switch couples the second boot node to the output node during a first portion of a second phase. A third switch couples to the first and second boot nodes for providing a conductive path through which charge can be shared between the first and second boot nodes during a second portion of the first and second phases.
