Abstract:
A sensor system includes a pixel array, column units and a compensation circuit. The pixel array is configured to provide pixel column data. The column units are configured to generate an offset data out signal from the pixel column data. The offset data out signal includes digital offsets. The compensation circuit is configured to remove the digital offsets from the offset data out signal. The compensation circuit is also configured to generate a data out signal.
