Abstract
A device that may include a pixel, an output conductor and a charge accelerator; wherein during a readout phase of the pixel, the pixel is configured to attempt to charge the output conductor to a pixel reset voltage and the charge accelerator is configured to perform a sampling operation and a charge operation; wherein during the sampling operation the charge accelerator is configured to sample a change in an output conductor voltage; wherein during the charge operation the charge accelerator is configured to output a charge accelerator output signal that is responsive to the change of the output conductor voltage, wherein once provided, the charge accelerator output signal accelerates a charging of the output conductor to a target voltage that is proximate to the pixel reset voltage; wherein the sampling operation and the charge operation do not overlap.
