    摘要: A fingerprint sensor interface that connects to a standard camera interface and minimizes input and output signals to reduce sensor die area and cost. The sensor can connect to a standard camera interface of a cellular telephone baseband processor or other device intended to receive signals from a camera. Input and output pad are arranged on a single edge of the die. Circuitry between the pads and the sensor active array creates clearance from the array to the bond wires connected to the pads.
