Abstract
A voltage booster circuit includes first and second capacitors and a switch circuit coupled to the first and second capacitors and operative to apply a power supply across the first and second capacitors in series responsive to a first signal to thereby charge the first and second capacitors and to couple the first and second capacitors in parallel between an output terminal and a power supply node of the power supply responsive to deassertion of the first signal and assertion of a second signal to thereby boost a voltage at the output terminal. The first and second signals may be alternately asserted in a succession of time periods, e.g., the first and second signals may be asserted in respective non-overlapping time periods.
