Notes
1. More information about CDS related signals is available in the following figures: The clamp current for pin CPCDS is
given in Fig. 9, clamp current for pins IND and INP in Fig 10 and for clamp current for pin Vref in Fig 11. The CDS
output amplitude is shown in Fig. 14
2. Noise measurement at ADC outputs: the coupling capacitor at the input is connected to ground, so that only the noise
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.
