    Abstract: A differential output stage of an amplification device, for driving a load, comprises a first and a second differential output stage portion. The first differential output stage portion comprises: a first and a second output circuit; a first driving circuit comprising a first biasing circuit; a second driving circuit comprising a second biasing circuit. The first differential output stage portion comprises: a third output circuit connected between a first node of said first biasing circuit and a first differential output terminal, having a third driving terminal connected to a first driving terminal; a fourth output circuit connected between a first node of the second biasing circuit and the first differential output terminal, having a fourth driving terminal connected to a second driving terminal.

    Abstract: A voltage level shifting device for driving a capacitive load has an input terminal for receiving a first input signal switchable between a first logic state corresponding to a first reference voltage and a second logic state corresponding to a second reference voltage, and an output terminal for supplying an output signal switchable between a first logic state corresponding to a third reference voltage and a second logic state corresponding to a fourth reference voltage. The device also has a first electronic circuit that is activated following a commutation of the first input signal from the first reference voltage to the second reference voltage for fixing the output terminal to the fourth reference voltage. The device further has a second electronic circuit that is activated following a commutation of the first input signal from the second reference voltage to the first reference voltage.
