Abstract
A 5.0 G-pixel/s readout circuit for 15.3 mm 8.6 mm
optical size, 3.7 M-pixel, 1300 fp s, and digital output image sensor
for industrial applications is presented. With the column parallel
ADC, the speed bottleneck is the vertical analog readout. To
achieve a 5.0 G-pixel/s readout rate, a high speed column readout
circuit is introduced. The novel pixel readout with the slew-en-
hancement and the time-interle aved correlated double sampling
circuit is introduced to increase the readout rate. Besid
