PGA 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 30 Mpixels with line of 1024 pixels of which the first 40 lines are used to run CLPOB and the last 40 lines for CLPDM. Data at the ADC outputs is
measured during the other pixels. As a result, the standard deviation of the codes statistic is computed, resulting in the noise. No quantization noise is
taken into account as there is no input.
