Abstract
An image sensor includes a photosensitive region that accumulates charge corresponding to received incident light; a transfer gate for transferring all or a portion of the charge from the photosensitive region; a voltage supply having an increasing voltage over time that is applied to the transfer gate; a floating diffusion for receiving the all or a portion of the charge from the photosensitive region and converting the charge to a voltage; an amplifier for receiving and amplifying a signal from the floating diffusion; a pulse detector for detecting a voltage pulse from the amplifier; and a counter for counting clock cycles between initiation of the increasing voltage until a signal is received from the detector which indicates initiation of charge transfer from the photosensitive region to the floating diffusion.
