KAF-09000
3056 (H) x 3056 (V) Full
Frame CCD Image Sensor
Description
Combining high resolution with outstanding sensitivity, the
KAF−09000 image sensor has been specifically designed to meet the
needs of next−generation low cost digital radiography and scientific
imaging systems. The high sensitivity available from 12−micron
square pixels combines with a low noise architecture to allow system
designers to improve overall image quality, or to relax system
tolerances to achieve lower cost. The excellent uniformity of the
KAF−09000 image sensor improves overall image integrity by
simplifying image corrections, while integrated anti−blooming
protection prevents image bleed from over−exposure in bright areas of
the image. To simplify device integration, the KAF−09000 image
sensor uses the same pin−out and package as the KAF−16801 image
sensor.
The sensor utilizes the TRUESENSE Transparent Gate Electrode to
improve sensitivity compared to the use of a standard front−side
illuminated polysilicon electrode.

Figure 3. Output Architecture (Left or Right)
The output consists of a floating diffusion capacitance
connected to a three−stage source follower. 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 current source must be added to the VOUT pin of
the device. See Figure 4.

1. Increasing output load currents to improve bandwidth will decrease these values.
2. Worst case deviation from straight line fit, between 1% and 90% of Vsat.
3. One Sigma deviation of a 128 x 128 sample when CCD illuminated uniformly.
4. Average of all pixels with no illumination at 25°C.
5. Read out dark current depends on the read out time, primarily when the vertical CCD clocks are at their high levels. This is approximately
0.125 sec/image for nominal timing conditions, tVw = 20 ms. The read out dark current will increase as tVw is increased. The readout dark
current is also dependent on the operating temperature. The specification applies to 25°C.
6. Average integration dark signal of any of 32 x 32 blocks within the sensor. (each block is 128 x 128 pixels)
7. Output amplifier noise only. Operating at pixel frequency up to 4 MHz, bandwidth <20 MHz, tint = 0, and no dark current shot noise.
8. 20log (Vsat/VN)
9. Xab is the number of times above the Vsat illumination level that the sensor will bloom by spot size doubling. The spot size is 10% of the
imager height. Xab is measured at 4 ms.
10. Video level offset with respect to ground.
11. A parameter that is measured on every sensor during production testing.
12. A parameter that is quantified during the design verification activity.
