Random noise
σ
CDS is defined as the standard deviation of a valid pixel output signal with 100 times (=100
lines) data sampling at dark (light shielding).
σ
CDS is calculated by the following procedure.
1. One valid photocell in one reading is fixed as measurement point.
2. The output level is measured during the reset feed-through period which is averaged over 100 ns to get
“VD
i
”.
3. The output level is measured during the video output time averaged over 100 ns to get “VO
i
”.
4. The correlated double sampling output is defined by the following formula.
VCDS
i
= VD

5. Repeat the above procedure (1 to 4) for 100 times (= 100 lines).
6. Calculate the standard deviation
