Abstract:
A booster circuit including:a first MOS transistor of a first conductivity type, a source of which is connected to a high voltage line;a second MOS transistor of a second conductivity type, a drain of which is connected to a first supply potential and a source of which is connected to a drain of the first transistor;a first capacitor connected between a gate of the first transistor and a reception terminal for a first clock signal;a second capacitor connected between a gate of the second transistor and the reception terminal of the first clock signal;a third capacitor connected between the drain of the first transistor and a reception terminal for a second clock signal, wherein the second clock signal is complementary to the first clock signal;a first one-way precharge means for precharging the first capacitor from the high voltage line, ensuring, during a precharge, that a voltage sufficient to turn on the first transistor is established between the source and the gate of said first transistor; anda second one-way precharge means for precharging the second capacitor.
