Abstract
A driving circuit supplied by a supply voltage and a reference voltage, generates an output signal and comprises a first circuit adapted to selectively couple the output signal to the reference voltage or to an internal voltage line internal to the driving circuit in response to a first control signal. The driving circuit also includes a switching circuit adapted to selectively couple the internal voltage line to the supply voltage. A boosting circuit is connected to the internal voltage line and is adapted to bring the internal voltage line to a boosted voltage. The switching circuit and the boosting circuit are controlled by a second control signal to be alternatively activatable, in such a way to bring the internal voltage line either to the supply voltage or to the boosted voltage.
