Abstract

A voltage booster comprising a charge pump for generating a boost voltage over a boost line. The booster comprises a comparator which is supplied by a voltage divider with a voltage proportional to the boost voltage, and by a reference source with a low reference voltage, and which, depending on the outcome of the comparison, enables or disables the charge pump. A voltage limiter is connected between the boost line and ground; and a acceleration circuit accelerates the voltage increase on the acceleration line following low-power operation in which the paths toward ground are interrupted for reducing consumption.
