Abstract
A semiconductor device comprising a fingerprint sensor configured to generate first-direction sensing data and second-direction sensing data by sensing a fingerprint image in a first direction and a second direction, respectively, which is perpendicular to the first direction; a differential sensing circuit configured to generate first-direction first differential data and second-direction first differential data by performing a differential operation on the first-direction sensing data and the second-direction sensing data, respectively; and a fingerprint processing circuit configured to generate first-direction second differential data and second-direction second differential data by performing a differential operation on the first-direction first differential data and the second-direction first differential data, respectively, and generate fingerprint data by adding the first-direction second differential data and the second-direction second differential data.
