Abstract
A circuit including a network of capacitors and switching transistors having two modes of functioning. The first mode isolates all the capacitors and simultaneously charges them to the level of the supply voltage. The second mode connects all these capacitors in series between the supply voltage Vdd and an output node of the network in order to instantaneously increase the voltage level of this output node to a voltage level that is greater than the supply voltage Vdd. The capacitors are all connected in series by transistors that are placed between them and controlled by a signal that has a peak voltage that is greater than the voltage to be switched to the output node of the network.
