A 3.7M-pixel 1300-fps CMOS image sensor with 5.0G-pixel/s high-speed readout circuit

Abstract

A 5.0G-pixel/s readout circuit for 15.3mm×8.6mm optical size, 3.7M-pixel, 1300 fps, and digital output image sensor is presented. To achieve 5.0G-pixel/s readout rate, the high speed column readout circuit is introduced. The novel pixel readout, A/D conversion, and digital data transfer schemes are introduced to realize the readout rate and to reduce the interference noise. The 1 horizontal (1H) readout time is realized to be 1.0μs.
