  • Capacitive fingerprint sensor
    Patent number: 9697410
    Abstract: A capacitive fingerprint sensor includes a compensation memory which stores a direct current offset parameter and a gain compensation parameter of each sensing unit of a capacitive sensing array. Therefore, the above-mentioned capacitive fingerprint sensor is able to individually compensate sensing signals measured by each the sensing unit and the sensing signals measured by each sensing unit have better uniformity and signal to noise ratio (SNR).
    Type: Grant
