Abstract :
A 2/3" 5 μm×5 μm pixel HDTV imager in a 0.25 μm CMOS process uses a tapered reset technique to suppress kT/C noise and supply 12b video with <15 e-read noise at 60, 72 and 90 Hz frame rates. Peak S/N ratio at 90 Hz (225 MHz video rate; 2.7 Gb/s at 12b/pixel) is 52 dB at standard scene illumination. Random noise at 18 dB gain is 8e-, independent of video frequency.
