Abstract: A circuit (125,130) for biasing an input node (Na) of a sense amplifier (115) is proposed. The circuit includes means (125) for keeping the input node at a pre-set operative voltage during a sensing operation; the circuit of the invention further includes means (250) for pulling the input node from a starting voltage towards a power supply voltage (+Vdd), the operative voltage being comprised between the starting voltage and the power supply voltage, and control means (255) for disabling the means for pulling before the input node reaches the operative voltage.
