AGC code
Noise measurement at ADC outputs:
Coupling capacitor at input is grounded, so only noise contribution of the front-end is evaluated. Front-end works at 18 Mpixels with line of 1024 pixels
whose first 40 are used to run CLPOB and the last 40 for CLPDM. Data at the ADC outputs are measured during the other pixels. As a result of this,
the standard deviation of the codes statistic is computed, resulting in the noise. No quantization noise is taken into account as no signal is inputted.
