Biasing (on-chip regulators)

Operating the pixel array requires multiple different biasing supply levels. These supply levels can be

generated using on-chip regulators. The chip contains 2 types of regulators, for positive supply levels

and negative supply levels. The regulator output voltages are controlled using the SPI interface.

The supply regulators are internally not connected to the actual image sensor. Connections have to be

made on PCB level (from a VxxREG pin to a Vyy pin). Also, each supply regulator requires to be
