A 2.2 Mpixel FT-CCD imager, according to the Eureka HDTV-standard

The first frame transfer CCD (charge coupled device) imager with 2.2 Mpixel, developed for use in HDTV (high-definition television) applications according to the Eureka HDTV standard, is reported with 1250 lines/frame, 1920 pixels/line, 50 fields/sec, aspect ratio of 16:9, and 2:1 interlacing. The image section of the CCD fits an optical system of 1 in., corresponding to a diagonal of 16 mm. The total chip area is 240 mm/sup 2/. This huge HDTV sensor has tackled successfully some typical technological challenges: high RC-value of the poly-silicon CCD gates; the high pixel count resulting in an output rate of 72 MHz; providing the device with a highly sensitive, low-noise, and high-bandwidth output amplifier; and a compact and efficient CCD cell combining the photo conversion, CCD transport, vertical anti-blooming, and electronic charge reset.<
