    摘要: The present disclosure relates to a voltage level shifting device (100; 200) for driving a capacitive load (C L ). The level shifting device comprises:
    - a first line set at a first reference voltage (GND);
    - a second line set at a second reference voltage (VDD1) greater than the first reference voltage (GND);
    - a third line set at a third reference voltage (VDD2) greater than the second reference voltage (VDD1).
    The device comprises an input terminal (N1) for receiving a first input signal (V IN ) switchable between a first logic state corresponding to the first reference voltage (GND) and a second logic state corresponding to the second reference voltage (VDD1), and an output terminal (102; 202) for supplying an output signal (V OUT ) switchable between a first logic state corresponding to the third reference voltage (VDD2) and a second logic state corresponding to a fourth reference voltage (VDD2-K) obtained by reducing the third reference voltage (VDD2) of a predetermined operative voltage (K).
