1.3.1.2 A/D architecture and Blooming Suppression
The On Semiconductor KAC-12040 and KAC-06040 image sensors have an analog to
digital converter on each column and built-in correction circuits that automatically
compensate and correct for fixed pattern noise within the image array. With an A/D
converter on each column of the imaging array, digitization occurs within each row
time rather than within a readout pixel time and this improves noise performance. Two
rows are readout simultaneously (one from the top of the array and one from the
