■ Construction of the Image Sensor
The MN3664 can be made up of the three sections of—a) photo
detector region, b) CCD transfer region (shift register), and c)
output region.
c) Output region
The signal transferred to this region is sent to the detector
region and is amplified by a two stage source follower
amplifier.
•
a) Photo detector region
• The photoelectric conversion device consists of a 5µm
floating photodiode and a 2µm channel stopper for each
pixel, and 5000 of these devices are linearly arranged side by
side at a pitch of 7µm.
Evaluation board
The placement of the each component is very important in order
to get a good output signal. The evaluation board BS803 is
available for evaluating the MN3664.
• The photo detector's windows are 7µm × 7µm squares and
light incident on areas other than these windows is optically
shut out.
• The photo detector is provided with 64 optically shielded
pixels which serve as the black reference.
b) CCD Transfer region (shift register)
The optical output after photoelectric conversion is
transferred respectively to the odd and even CCD transfer
region at the timing of the shift gate electrode (ø SG), the
photoelectric converted output transferred to this analog shift
register is transferred successively to the output region.
•
buried type CCD that can be driven by a 2-phase clock is
• A
used as the analog shift register.
