摘要：The capacitive fingerprint sensor according to the exemplary embodiments ofthe present invention includes: a fingerprint sensing electrode Cfp for sensing a humanfingerprint; a first transistor T in which the amount of currents flowing therethroughchanges depending on an output voltage of the fingerprint sensing electrode Cfp; a

second transistor T in which the amount of currents flowing therethrough changes due toa difference between the currents flowing through the first transistor T; and a thirdtransistor T which resets a gate electrode of the first transistor T and provides capacitivecoupling with the gate electrode of the first transistor T via a pulse signal.
