The results were obtained using 530 nm illumination. The ADC ramp gain was adjusted to the equivalent of 1 V swing,

for 12-bit ADC mode, and 0.5 V swing for 8-bit ADC mode (therefore, approximately half of FWC for 8-bit). The sensors

temperature was approximately 60ºC (uncontrolled temperature environment). The values presented are for the default

configuration of Full Well around 20 ke- (STS3 Register bits [3:0] = 0x0). Sensor supply levels were the typical ones:

VDDA = 3.3 V and VDDD = 1.8 V. The set Readout mode was 1-To-1. DSNU and PRNU results were characterized for

each variant. The remaining parameters are valid for all variants, once they all share the same silicon.

The settings used to get these values are those recommended by the European Machine Vision Association standard

1288 from the Machine Vision Sensors and Cameras. https://www.emva.org/standards-technology/emva-1288/
