A 1/4.5in 3.1M pixel FT-CCD with 1.56 /spl mu/m pixel size for mobile applications

The frame-transfer CCD (FT-CCD) achieves a saturation signal voltage of 270mV and a sensitivity of 280mV/lx-s in full-resolution still mode. The sensor can also operate in a 30f/s VGA with a movie mode with saturation signal voltage of 1040mV and a sensitivity of 960mV/lx-s. A 9-phase vertical transfer technique reduces smear signals to -75dB.
