Abstract

This paper describes a 2.2 Megapixel CMOS image sensor made in 0.18 μm CMOS process for high-speed machine vision applications. The sensor runs at 340 fps with digital output using 16 LVDS channels at 480MHz. The pixel array counts 2048x1088 pixels with a 5.5um pitch. The unique pixel architecture supports a true correlated double sampling, thus yields a noise level as low as 13 e- and a pixel parasitic light sensitivity (PLS) of 1/60 000. The sensitivity of the sensor is measured to be 4.64 Vlux.s and the pixel full well charge is 18k e-.
