Abstract:
1. A single-stage clock booster for producing a boosted clock voltage on an output node that is a multiple of a supply voltage, the single-stage clock booster comprising: a pump capacitor having a first terminal being driven by a first control phase signal, and a second terminal; a first switch controlled by the boosted clock voltage for connecting the second terminal of said pump capacitor to the supply voltage during a charge phase; a second switch for connecting the second terminal of said pump capacitor to the output node during a boosted clock voltage output phase, said second switch having a control node; a switching circuit for alternately connecting the control node of said second switch to the supply voltage and to the first terminal of said pump capacitor, said switching circuit being driven by a second control phase signal; a third switch controlled by a third control phase signal for connecting the output node to a reference voltage during the charge phase; and a generator for generating the first, second and third control phase signals for alternately connecting the second terminal of said pump capacitor to the supply voltage and to the output node, and for connecting the first terminal of said pump capacitor to the reference voltage and to the supply voltage respectively.
