    Abstract: A fingerprint detection device including a sensor array including a plurality of fingerprint sensor elements arranged in a form of a matrix having a plurality of rows and columns, a filter and buffer unit including a plurality of first banks, each of which is configured to perform a noise elimination operation and a temporal storage operation in parallel with respect to output signals of some different columns of the sensor array. Each of the plurality of first banks simultaneously or consecutively acquires output signals from the fingerprint sensor elements belonging to columns spaced apart from each other by a predetermined distance. A sample and hold unit including second banks, the number of which being the same as the number of the plurality of first banks, performs a sampling and hold function in parallel in response to output signals from the plurality of first banks. An input/output unit receives an output signal from the sample and hold unit to output data of the sensor array.
