CCD Linear Image Sensor
Construction of the Image Sensor
The MN3610 can be made up of the three sections of—a)
photo detector region, b) CCD transfer region (shift register),
and c) output region.
a) Photo detector region
The photoelectric conversion device consists of an 11µm
floating photodiode and a 3µm channel stopper for each
pixel, and 2048 of these devices are linearly arranged side
by side at a pitch of 14µm.
The photo detector's windows are 14µm 14µm squares and
light incident on areas other than these windows is optically
shut out.
The photo detector is provided with 52 optically shielded
pixels (black dummy pixels) which serve as the black
reference.
b) CCD Transfer region (shift register)
The light output that has been photoelectrically converted is

electric charge transferred to this analog shift register is
successively transferred out and guided to the output region.
A buried type CCD that can be driven by a two phase clock

c) Output region
The signal charge that is transferred to the output region is
sent to the detector where impedance transformation is done
using two source follower stages.
The DC level component and the clock noise component not
containing optical signals are output from the DS pin.
By carrying out differential amplification of the two outputs
OS and DS externally, it is possible to obtain an output signal
with a high S/N ratio by reducing the clock noise, etc.
