voltage.

Note 8: DC signal output voltage is defined as follows.

Reset Noise Voltage is defined as follows.

Note 9: Random noise is defined as the standard deviation (sigma) of the output level difference between two

adjacent effective pixels under no illumination (i.e. dark conditions) calculated by the following procedure.

1)

Two adjacent pixels (pixel n and n

+ 1) in one reading are fixed as measurement points.

2)

Each of the output level at video output periods averaged over 200ns period to get V (n) and V (n

+ 1).

3)

V (n

+ 1) is subtracted from V (n) to get DV.

DV = V (n) - V (n + 1)

4)

The standard deviation of

DV is calculated after procedure 2) and 3) are repeated 30 times (30

readings).
