Abstract
For clamping a reset voltage within an image sensor, an active pixel generates a first reset voltage, and an optical black pixel generates a second reset voltage. In addition, a reset voltage selector selects one of the first and second reset voltages as a selected reset voltage. Such a selected reset voltage is generated separately for each column of the array of pixels in the image sensor for more accurately and flexibly accounting for fabrication variations.
