The paper describes a large format 4 Megapixel (2352 x 1728) sensor with on-chip parallel 10 bit ADCs. The chip size is 20 x 20 mm with 7 μm pixel pitch. It achieves a high frame rate of 240 frames/s delivering 9.75 Gbit of data per second. The sensor also features an additional fixed pattern noise cancellation circuitry. The sensor operation voltage is 3.3 V with power dissipation of ~1 W at master clock rate of 66 MHz. Principal architecture of the sensor is discussed along with the results of its characterization.
