Mheen, B. (author), Song, Y.J. (author), Theuwissen, J.P. (author)This letter presents an electrical method to reduce dark current as well as increase well capacity of four-transistor pixels in a CMOS image sensor, utilizing a small negative offset voltage to the gate of the transfer (TX) transistor particularly only when the TX transistor is off. As a result, using a commercial pixel in a 0.18 ?m CMOS process...journal article 2008
