Abstract: Provided is a fingerprint sensor. The fingerprint sensor according to an embodiment of the inventive concept includes a plurality of transmission lines, a plurality of receive lines, and a sensor array including sensor units connected to the plurality of transmission lines. Each of the sensor units includes a switch transistor having a gate terminal and one terminal, which are commonly connected to a corresponding transmission line of the plurality of transmission lines and a sensor transistor connected between the other end of the switch transistor and a corresponding receive line of the plurality of receive lines. The sensor transistor performs a current suppression on in response to a voltage of a virtual gate that is touched by a fingerprint.
