Abstract
A single-stage clock booster produces a boosted clock voltage on an output node that is a multiple of a supply voltage. The single-stage clock booster includes a pump capacitor having a first terminal being driven by a first control phase signal. A first switch is controlled by the boosted clock voltage for connecting a second terminal of the pump capacitor to the supply voltage during a charge phase. A second switch connects the second terminal of the pump capacitor to the output node during a boosted clock voltage output phase. A switching circuit alternately connects a control node of the second switch to the supply voltage and to the first terminal of the pump capacitor. The switching circuit is driven by a second control phase signal. A third switch is controlled by a third control phase signal for connecting the output node to a reference voltage during the charge phase.
