摘要：

A 5.0 G-pixel/s readout circuit for 15.3 mm x 8.6 mm optical size, 3.7 M-pixel, 1300 fps, 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-enhancement and the time-interleaved correlated double sampling circuit is introduced to increase the readout rate. Besides, the A/D converter with the delay-and-gray code counter and the distributed digital data transfer schemes are innovated in order to reduce the noise interference to the foreground analog signal settling. The 1 horizontal (1H) readout time is 1.0 mu s.
