CCD Image Sensor
Description
The KAI−2001 Image Sensor is a high-performance 2-million pixel
sensor designed for a wide range of medical, scientific and machine
vision applications. The 7.4 mm square pixels with microlenses
provide high sensitivity and the large full well capacity results in high
dynamic range. The split horizontal register offers a choice of single or
dual output allowing either 15 or 30 frame per second (fps) video rate
for the progressively scanned images. Also included is a fast line
dump for sub-sampling at higher frame rates. The vertical overflow
drain structure provides anti-blooming protection and enables
electronic shuttering for precise exposure control. Other features
include low dark current, negligible lag and low smear.

There are 2 light shielded rows followed 1,208
photoactive rows and finally 4 more light shielded rows.
The first 4 and the last 4 photoactive rows are buffer rows
giving a total of 1,200 lines of image data.
In the single output mode all pixels are clocked out of the
Video L output in the lower left corner of the sensor. The first
4 empty pixels of each line do not receive charge from the
vertical shift register. The next 16 pixels receive char ge from
the left light shielded edge followed by 1,608 photosensitive
pixels and finally 16 more light shielded pixels from the
right edge of the sensor. The first and last 4 photosensitive
pixels are buffer pixels giving a total of 1,600 pixels of
image data.
In the dual output mode the clocking of the right half of the
horizontal CCD is reversed. The left half of the image is
clocked out V ideo L and the right half of the image is clocked
out Video R. Each row consists of 4 empty pixels followed
by 16 light shielded pixels followed by 800 photosensitive
pixels. When reconstructing the image, data from Video R
will have to be reversed in a line buf fer and appended to the
Video L data.
There are 4 dark reference rows at the top and 2 dark rows
at the bottom of the image sensor. The dark rows are not
entirely dark and so should not be used for a dark reference
level. Use the 16 dark columns on the left or right side of the
image sensor as a dark reference.
Of the 16 dark columns, the first and last dark columns
should not be used for determining the zero signal level.
Some light does leak into the first and last dark columns.
Only use the center 14 columns of the 16 column dark
reference.

n Substrate
An electronic representation of an image is formed when
incident photons falling on the sensor plane create
electron-hole pairs within the individual silicon
photodiodes. These photoelectrons are collected locally by
the formation of potential wells at each photosite. Below
photodiode saturation, the number of photoelectrons
collected at each pixel is linearly dependent upon light level
and exposure time and non-linearly dependent on
wavelength. When the photodiodes charge capacity is
reached, excess electrons are discharged into the substrate to
prevent blooming.

When the V1 and V2 timing inputs are pulsed, charge in
every pixel of the VCCD is shifted one row towards the
HCCD. The last row next to the HCCD is shifted into the
HCCD. When the VCCD is shifted, the timing signals to the
HCCD must be stopped. H1 must be stopped in the high state
and H2 must be stopped in the low state. The HCCD
clocking may begin tHD ms after the falling edge of the V1
and V2 pulse.
Charge i s transferred from the last vertical CCD phase into
the H1S horizontal CCD phase. Refer to Figure 27 for an
example of timing that accomplishes the vertical to
horizontal transfer of charge.
If the fast line dump is held at the high level (FDH) during
a vertical to horizontal transfer, then the entire line is
removed and not transferred into the horizontal register.

The HCCD has a total of 1,648 pixels. The 1,640 vertical
shift registers (columns) are shifted into the center 1,640
pixels of the HCCD. There are 4 pixels at both ends of the
HCCD, which receive no charge from a vertical shift
register. The first 4 clock cycles of the HCCD will be empty
pixels (containing no electrons). The next 16 clock cycles
will contain only electrons generated by dark current in the
VCCD and photodiodes. The next 1,608 clock cycles will
contain photo-electrons (image data). Finally, the last 16
clock cycles will contain only electrons generated by dark
current in the VCCD and photodiodes. Of the 16 dark
columns, the first and last dark columns should not be used
for determining the zero signal level. Some light does leak
into the first and last dark columns. Only use the center 14
columns of the 16 column dark reference.
When the HCCD is shifting valid image data, the timing
inputs to the electronic shutter (SUB), VCCD (V1, V2),
and fast line dump (FD) should be not be pulsed. This
prevents unwanted noise from being introduced. The HCCD
is a type of charge coupled device known as a pseudo-two
phase CCD. This type of CCD has the ability to shift charge
in two directions. This allows the entire image to be shifted
out to the video L output, or to the video R output (left/right
image reversal). The HCCD is split into two equal halves of
824 pixels each. When operating the sensor in single output
mode the two halves of the HCCD are shifted in the same
direction. When operating the sensor in dual output mode
the two halves of the HCCD are shifted in opposite
directions. The direction of charge transfer in each half is
controlled by the H1BL, H2BL, H1BR, and H2BR timing
inputs.

Single Output Operation
When operating the sensor in single output mode all pixels
of the image sensor will be shifted out the Video L output
(pin 31). To conserve power and lower heat generation the
output amplifier for Video R may be turned off by
connecting VDDR (pin 24) and VOUTR (pin 24) to GND
(zero volts).
The H1 timing from the timing diagrams should be
applied to H1SL, H1BL, H1SR, H2BR, and the H2 timing
should be applied to H2SL, H2BL, H2SR, and H1BR. In
other words, the clock driver generating the H1 timing
should b e connected to pins 4, 3, 13, and 15. The clock driver
generating the H2 timing should be connected to pins 5, 2,
12, and 14. The horizontal CCD should be clocked for 4
empty pixels plus 16 light shielded pixels plus 1,608
photoactive pixels plus 16 light shielded pixels for a total o f
1,644 pixels.
Dual Output Operation
In dual output mode the connections to the H1BR and
H2BR pins are swapped from the single output mode to
change the direction of charge transfer of the right side
horizontal shift register. In dual output mode both VDDL
and VDDR (pins 25, 24) should be connected to 15 V.
The H1 timing from the timing diagrams should be applied
to H1SL, H1BL, H1SR, H1BR, and the H2 timing should be
applied t o H2SL, H2BL, H2SR, and H2BR. The clock driver
generating the H1 timing should be connected to pins 4, 3,
13, and 14. The clock driver generating the H2 timing should
be connected to pins 5, 2, 12, and 15. The horizontal CCD
should be clocked for 4 empty pixels plus 16 light shielded
pixels plus 804 photoactive pixels for a total of 824 pixels.
If the camera is to have the option of dual or single output
mode, the clock driver signals sent to H1BR and H2BR may
be swapped by using a relay. Another alternative is to have
two extra clock drivers for H1BR and H2BR and invert the
signals in the timing logic generator. If two extra clock
drivers are used, care must be taken to ensure the rising and
falling edges of the H1BR and H2BR clocks occur at the
same time (within 3 ns) as the other HCCD clocks.

Charge packets contained in the horizontal register are
dumped pixel by pixel onto the floating diffusion (FD)
output node whose potential varies linearly with the quantity
of charge in each packet. The amount of potential charge is
determined by the expression DVFD =DQ/C
FD.
A three-stage source-follower amplifier is used to buffer
this signal voltage of f chip with slightly less than unity gain.
The translation from the charge domain to the voltage
domain is quantified by the output sensitivity or charge to
voltage conversion in terms of microvolts per electron
(mV/e). After the signal has been sampled off chip, the reset
clock (R) removes the char ge from the floating dif fusion and
resets its potential to the reset drain voltage (RD).
When the image sensor is operated in the binned or
summed interlaced modes ther e w il l be mo re tha n 4 0, 000 e
in the output signal. The image sensor is designed with
a16mV/e charge to voltage conversion on the output. This
means a full signal of 40,000 electrons will produce
a 640 mV change on the output amplifier. The output
amplifier was designed to handle an output swing of 640 mV
at a pixel rate of 40 MHz. If 80,000 electron charge packets
are generated in the binned or summed interlaced modes
then the output amplifier output will have to swing
1,280 mV. The output amplifier does not have enough
bandwidth (slew rate) to handle 1,280 mV at 40 MHz.
Hence, the pixel rate will have to be reduced to 20 MHz if
the full dynamic range of 80,000 electrons is desired.
The charge handling capacity of the output amplifier is
also set by the reset clock voltage levels. The reset clock
driver circuit is very simple if an amplitude of 5 V is used.
But the 5 V amplitude restricts the output amplifier charge
capacity to 40,000 electrons. If the full dynamic range of
80,000 electrons is desired then the reset clock amplitude
will have to be increased to 7 V.
If you only want a maximum signal of 40,000 electrons in
binned or summed interlaced modes, then a 40 MHz pixel
rate with a 5 V reset clock may be used. The output of the
amplifier will be unpredictable above 40,000 electrons so be
sure to set the maximum input signal level of your analog to
digital converter to the equivalent of 40,000 electrons
(640 mV).

Dark Field Center Non-Uniformity
This test is performed under dark field conditions. Only
the center 100 by 100 pixels of the sensor are used for this
test − pixel (750, 550) to pixel (849, 649).

Units: mV rms. DPS Integration Time: Device Performance Specification Integration Time = 33 ms.
Dark Field Global Non-Uniformity
This test is performed under dark field conditions.
The sensor is partitioned into 192 sub regions of interest,
each of which is 100 by 100 pixels in size. See Figure 17.
The average signal level of each of the 192 sub regions of
interest is calculated. The signal level of each of the sub
regions of interest is calculated using the following formula:
Signal of ROI[i] +(ROI Average in ADU *
Units : mVpp (millivolts Peak to Peak)
*Horizontal Overclock Average in ADU) @
@mV per Count
Where i = 1 to 192. During this calculation on the 192 sub
regions of interest, the maximum and minimum signal levels
are found. The dark field global uniformity is then calculated
as the maximum signal found minus the minimum signal
level found.

This test is performed with the imager illuminated to
a level such that the output is at 80% of saturation

Dark Field Defect Test
This test is performed under dark field conditions.
The sensor is partitioned into 192 sub regions of interest,
each of which is 100 by 100 pixels in size (see Figure 17).
In each region of interest, the median value of all pixels is
found. For each region of interest, a pixel is marked
defective if it is greater than or equal to the median value of
that region of interest plus the defect threshold specified in
“Defect Definitions” section.
Bright Field Defect Test
This test is performed with the imager illuminated to
a level such that the output is at 80% of saturation
(approximately 32,000 electrons). Prior to this test being
performed the substrate voltage has been set such that the
charge capacity of the sensor is 40,000 electrons.
The average signal level of all active pixels is found.
The bright and dark thresholds are set as:
Dark Defect Threshold = Active Area Signal @Threshold
Bright Defect Threshold = Active Area Signal @Threshold
The sensor is then partitioned into 192 sub regions of
interest, each of which is 100 by 100 pixels in size (see
Figure 17). In each region of interest, the average value of
all pixels is found. For each region of interest, a pixel is
marked defective if it is greater than or equal to the median
value of that region of interest plus the bright threshold
specified or if it is less than or equal to the median value of
that region of interest minus the dark threshold specified.
Example for major bright field defective pixels:
Average value of all active pixels is found to be
416 mV (32,000 electrons).
Dark defect threshold: 416 mV 15% = 62.4 mV.
Bright defect threshold: 416 mV 15% = 62.4 mV.
Region of interest #1 selected. This region of interest is
pixels 1, 1 to pixels 100, 100.
Median of this region of interest is found to be
416 mV.
Any pixel in this region of interest that is
(416 + 62.4 mV) 478.4 mV in intensity will be
marked defective.
Any pixel in this region of interest that is
(416 62.4 mV) 353.6 mV in intensity will be
marked defective.
All remaining 191 sub regions of interest are analyzed
for defective pixels in the same manner.

Electronic Shutter Description
The voltage on the substrate (SUB) determines the charge
capacity of the photodiodes. When SUB is 8 V the
photodiodes will be at their maximum charge capacity.
Increasing VSUB above 8 V decreases the charge capacity
of the photodiodes until 48 V when the photodiodes have
a charge capacity of zero electrons. Therefore, a short pulse
on SUB, with a peak amplitude greater than 48 V, empties
all photodiodes and provides the electronic shuttering
action.
It may appear the optimal substrate voltage setting is 8 V
to obtain the maximum charge capacity and dynamic range.
While setting VSUB to 8 V will provide the maximum
dynamic range, it will also provide the minimum
anti-blooming protection.
The KAI−2001 VCCD has a charge capacity of
55,000 electrons ( 5 5 ke). If the SUB voltage is set such that
the photodiode holds more than 55 ke, then when the
charge is transferred from a full photodiode to VCCD,
the VCCD will overflow. This overflow condition manifests
itself in the image by making bright spots appear elongated
in the vertical direction. The size increase of a bright spot is
called blooming when the spot doubles in size.
The blooming can be eliminated by increasing the voltage
on SUB to lower the charge capacity of the photodiode. This
ensures the VCCD charge capacity is greater than the
photodiode capacity. There are cases where an extremely
bright spot will still cause blooming in the VCCD. Normally,
when the photodiode is full, any additional electrons
generated by photons will spill out of the photodiode.
The excess electrons are drained harmlessly out to the
substrate. There is a maximum rate at which the electrons
can be drained to the substrate. If that maximum rate is
exceeded, (for example, by a very bright light source) then
it is possible for the total amount of charge in the photodiode
to exceed the VCCD capacity. This results in blooming.
The amount of anti-blooming protection also decreases
when the integration time is decreased. There is
a compromise between photodiode dynamic range
(controlled by VSUB) and the amount of anti-blooming
protection. A low VSUB voltage provides the maximum
dynamic range and minimum (or no) anti-blooming
protection. A high VSUB voltage provides lower dynamic
range and maximum anti-blooming protection. The optimal
setting of VSUB is written on the container in which each
KAI−2001 is shipped. The given VSUB voltage for each
sensor is selected to provide anti-blooming protection for
bright spots at least 100 times saturation, while maintaining
at least 40 ke of dynamic range.
The electronic shutter provides a method of precisely
controlling the image exposure time without any
mechanical components. If an integration time of tINT is
desired, then the substrate voltage of the sensor is pulsed to
at least 40 V tINT seconds before the photodiode to VCCD
transfer pulse on V2. Use of the electronic shutter does not
have to wait until the previously acquired image has been
completely read out of the VCCD.
Large Signal Output
When the image sensor is operated in the binned or
summed interlaced modes there will be more than
40,000 electrons in the output signal. The image sensor is
designed with a 16 mV/e charge to voltage conversion on the
output. This means a full signal of 40,000 electrons will
produce a 640 mV change on the output amplifier.
The output amplifier was designed to handle an output
swing of 640 mV at a pixel rate of 40 MHz. If 80,000
electron charge packets are generated in the binned or
summed interlaced modes then the output amplifier output
will have to swing 1,280 mV. The output amplifier does not
have enough bandwidth (slew rate) to handle 1,280 mV at
40 MHz. Hence, the pixel rate will have to be reduced to
20 MHz if the full dynamic range of 80,000 electrons is
desired.
The charge handling capacity of the output amplifier is
also set by the reset clock voltage levels. The reset clock
driver circuit is very simple if an amplitude of 5 V is used.
But the 5 V amplitude restricts the output amplifier charge
capacity to 40,000 electrons. If the full dynamic range of
80,000 electrons is desired then the reset clock amplitude
will have to be increased to 7 V.
If you only want a maximum signal of 40,000 electrons in
binned or summed interlaced modes, then a 40 MHz pixel
rate with a 5 V reset clock may be used. The output of the
amplifier will be unpredictable above 40,000 electrons so be
sure to set the maximum input signal level of your analog to
digital converter to the equivalent of 40,000 electrons
(640 mV).
