Abstract
An image sensor includes a plurality of photodiodes disposed in a semiconductor material and a plurality of transfer transistors. Individual transfer transistors in the plurality of transfer transistors are coupled to individual photodiodes in the plurality of photodiodes. A floating diffusion is also coupled to the plurality of transfer transistors to receive image charge from the plurality of photodiodes. The floating diffusion is coupled to receive a preset voltage, and the preset voltage is substantially equal a dark condition steady-state read voltage.
