Abstract
A digital imaging system includes an array of sensors arranged generally in rows and columns and having data lines coupled to the sensors. Receiving logic is coupled to sense voltages on the data lines. A reference voltage generator (which can include a resistor network) generates a plurality of reference voltages in the digital imaging system in response to an applied differential voltage. A test row of sensors are electrically coupled to corresponding reference voltages, each test sensor coupled to a data line and receiving a voltage based on its coupled reference voltage. The receiving logic includes at least one A/D converter that reads the test sensor voltage value and converts it to a digital value.
