Abstract

The authors describe an interline transfer charge coupled device (CCD) area image sensor with 94-dB dynamic range and 1.0-electron RMS noise charge detector. With a new capacitance-coupled negative-feedback configuration, the saturation level of the detector is successfully extended by a factor of five, maintaining the superior low-noise characteristics. The imager with this detector has 398 (H)×492 (V) pixels in 1/3-in format image size. Moreover, 1/f noise in the output signal is successfully suppressed with a new alternate gain inversion (AGI) signal processing
