contribution of the front-end is evaluated. The front-end operates at 18 Mpix with a line of 1024 pixels. The first 40 are
used to run CLPOB and the last 40 to run CLPDM. Data at the ADC outputs is measured during the other pixels.
The differences between the types of codes statistic is then computed; the result is the noise. No quantization noise
is taken into account as no signal is input. Figure 15 gives noise figure graphs with signal input.
