High-speed VGA CMOS image sensor

摘要

We present some design details and characterization results for a VGA CMOS image sensor designed for high speed inspection applications. The sensor has 16 analog outputs, which can each operate at 50 MHz data rate, and can capture images at 1600 frames per second. Th image sensor has exposure control functionality, antiblooming capability and a non-rolling shutter architecture to implement snap-shot image capture mode. The pixel architecture incorporates 5 transistors on a 15.3 micron pitch with 50% fill factor.
