KAF-6303
3072 (H) x 2048 (V) Full Frame CCD Image Sensor
Description
The KAF−6303 Image Sensor is a high performance CCD (charge-coupled device) with 3072 (H) × 2048 (V) photo active pixels designed for a wide range of image sensing applications.
The sensor incorporates true two-phase CCD technology, simplifying the support circuits required to drive the sensor as well as reducing dark current without compromising charge capacity. The sensor also utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode.

The sensor consists of 3,088 parallel (vertical) CCD shift registers each 2,056 elements long. These registers act as both the photosensitive elements and as the transport circuits that allow the image to be sequentially read out of the sensor. The elements of these registers are arranged into a 3,072 × 2,048 photosensitive array surrounded by a light shielded dark reference of 16 columns and 8 rows. The parallel (vertical) CCD registers transfer the image one line at a time into a single 3,100 element (horizontal) CCD shift register. The horizontal register transfers the charge to a single output amplifier. The output amplifier is a two-stage source follower that converts the photo-generated charge to a voltage for each pixel.
Dark Reference Pixels Surrounding the peripheral of the device is a border of
light shielded pixels. This includes 6 leading and 10 trailing pixels on every line excluding dummy pixels. There are also 4 full dark lines at the start of every frame and 4 full dark lines at the end of each frame. Under normal circumstances, these pixels do not respond to light. However, dark reference pixels in close proximity to an active pixel, or the outer bounds of the chip (including the first two lines out), can scavenge signal depending on light intensity and wavelength and therefore will not represent the true dark signal.
Dummy Pixels Within the horizontal shift register are 10 leading and 2
trailing additional shift phases that are not associated with a column of pixels from the vertical register. These pixels
contain only horizontal shift register dark current signal and do not respond to light. A few leading dummy pixels may scavenge false signal depending on operating.
