Píxel con intervalo dinámico ajustable para la reducción del ruido

A pixel of an image sensor is provided, the pixel comprising: a photodiode connected to a primary sensing node (SN1) via a transfer gate; a secondary sensing node (SN2); an attenuator connected between the primary sensing node and the secondary sensing node having an attenuation factor selected to convert a first input voltage range to a second output voltage range; a first reset switch for resetting the sensing node to a first selected supply voltage (VDC1); a second reset switch for resetting the sensing node (SN2) to a second selected supply voltage (VDC2); and an amplification stage comprising a first amplifier comprising a first low noise transistor having a gate connected to the secondary sensing node, a selection switch for sampling the output signal of the amplification stage.
