Abstract
A technique for generating an adjustable boost voltage for a device includes charging, using first and second switches, a capacitor to a first voltage during a charging phase. The technique also includes stacking, using a third switch, a second voltage onto the first voltage across the capacitor in a boost phase to generate a boost voltage. In this case, the boost voltage is applied to a driver circuit of the device only during the boost phase and at least one of the first and second voltages is adjustable, thereby making the boost voltage adjustable.
