256x256 pixel CMOS imager with linear readout and 120dB dynamic range

In this contribution, a 256x256 pixel CMOS imager is described, which features linear readout, 120dB dynamic range (DR), 56dB signal-to-noise ratio, 65% filling factor, and an effective frame rate of 50 Hz. The imager has been integrated in 1µm double-metal CMOS technology. Sample images exhibiting high DR are presented and compared to those taken with a conventional CCD imager.
