We have developed a 1/2-inch 1.3M-pixel progressive-scan interline-transfer CCD image sensor. It provides both 15 frames/sec 1O50-line progressive color pictures and 30 frames/sec 525-line progressive color pictures. A two-phase drive horizontal CCD with phosphorus-implanted storage regions helps reduce the driving voltage to 2.5 V. A source-follower amplifier with separate p-well driver transistors achieves a gain 12% higher than that of a conventional amplifier. This sensor is useful in producing small size, low cost, and high resolution digital still cameras for consumer multimedia applications.
