KAF-8300
3326 (H) x 2504 (V) Full
Frame CCD Image Sensor
Description
The KAF−8300 Image Sensor is a 22.5 mm diagonal (Four Thirds
Format) high performance color or monochrome full frame CCD
(charge-coupled device) image sensor designed for a wide range of
image sensing applications including digital imaging. Each pixel
contains blooming protection by means of a lateral overflow drain
thereby preventing image corruption during high light level
conditions. For the color version, the 5.4 mm square pixels are
patterned with an RGB mosaic color filter with overlying microlenses
for improved color response and reproduction. Several versions of
monochrome devices are available with or without microlenses.

non-uniformities. The response of these pixels will not be
uniform.
For monochrome devices, 20 buffer pixels adjacent to the
dark dummy pixels are classified as active buffer pixels.
These pixels are light sensitive but they are not tested for
defects and non-uniformities. The response of these pixels
will not be uniform.
Blue Pixel Buffer
For color devices, four buffer pixels adjacent to any
leading or trailing dark reference regions contain a blue filter
and is classified as a blue pixel buffer. These pixels are light
sensitive but they are not tested for defects and
non-uniformities. The response of these pixels will not be
uniform.
Monochrome devices do not contain a blue pixel buffer.
CTE Monitor Pixels
Within the horizontal dummy pixel region two light
sensitive test pixels (one each on the leading and trailing
ends) are added and within the vertical dummy pixel region
one light sensitive test pixel has been added. These CTE
monitor pixels are used for manufacturing test purposes. In
order to facilitate measuring the device CTE, the pixels in
the CTE Monitor region in the horizontal and vertical
portion is coated with blue pigment on the color version
only. The monochrome device is uncoated).
Image Acquisition
An electronic representation of an image is formed when
incident photons falling on the sensor plane create
electron-hole pairs within the device. These photon-induced
electrons are collected locally by the formation of potential
wells at each photogate or pixel site. The number of
electrons collected is linearly dependent on light level and
exposure time and non-linearly dependent on wavelength.
When the pixel’s capacity is reached, excess electrons are
discharged into the lateral overflow drain to prevent
crosstalk or ‘blooming’. During the integration period, the
V1 and V2 register clocks are held at a constant (low) level.
Charge Transport
The integrated charge from each photogate is transported
to the output using a two-step process. Each line (row) of
charge is first transported from the vertical CCD’s to
a horizontal CCD register using the V1 and V2 register
clocks. The horizontal CCD is presented a new line on the
falling edge of V2 while H1 is held high. The horizontal
CCD’s then transport each line, pixel by pixel, to the output
structure by alternately clocking the H1 and H2 pins in
a complementary fashion. A separate connection to the last
H1 phase (H1L) is provided to improve the transfer speed of
charge to the floating diffusion. On each falling edge of H1
a new charge packet is dumped onto a floating diffusion and
sensed by the output amplifier.
Horizontal Register
Output Structure
Charge presented to the floating diffusion (FD) is
converted into a voltage and is current amplified in order to
drive off-chip loads. The resulting voltage change seen at the
output is linearly related to the amount of charge placed on
the FD. Once the signal has been sampled by the system
electronics, the reset gate (RG) is clocked to remove the
signal and FD is reset to the potential applied by reset drain
(RD). Increased signal at the floating diffusion reduces the
voltage seen at the output pin. To activate the output
structure, an off-chip load must be added to the VOUT pin
of the device. See Figure 5.
