the black level is still inside the range of the ADC after amplifi-
cation. The result after amplification is the purple histogram

Operation and Signaling
Power Supplies
Every module on chip such as column amplifiers, output stages,
digital modules, and drivers has its own power supply and
ground. Off chip the grounds can be combined, but not all power
supplies may be combined. This results in several different
power supplies, but this is required to reduce electrical cross-talk
and to improve shielding, dynamic range, and output swing.
On chip, the ground lines of every module are kept separate to
improve shielding and electrical cross-talk between them.
An overview of the supplies is given in

Note that no power supply filtering on chip is implemented and
that noise on these power supplies can contribute immediately
to the noise on the signal. The voltage supplies V
