    Abstract: An analog signal generation circuit is provided. The analog signal generation circuit includes a first control section that generates a first control signal; a second control section that generates a second control signal; current cells, each of the plurality of current cells controlled to generate current or to not generate current based on the first and second control signals; and an analog signal output section that outputs an analog signal generated based on current generated by the current cells. The first control signal includes first and second cell state setting signals. A logical value corresponding to the first cell state setting signal is complementary to a logical value corresponding to the second cell state setting signal. Each current cell has an initialized state based on the first cell state setting signal.

    Abstract: An electronic device is provided. The electronic device includes a display, a fingerprint sensor disposed on one surface of the display, a memory storing a plurality of fingerprint images mapped to information indicative of a plurality of guide lines, and a processor operatively connected to the display, the fingerprint sensor, and the memory. The processor may be configured to display a first user interface (UI) indicative of a fingerprint recognition area and, as a second UI, a guide line corresponding to a fingerprint image having a high quality value among the plurality of fingerprint images stored in the memory by using the display, based on an input signal to request fingerprint authentication being detected, obtain a fingerprint image of a finger by using the fingerprint sensor based on the finger of a user touching the fingerprint recognition area, compare the obtained fingerprint image and a fingerprint image mapped to information indicative of the first UI and/or the second UI, and perform the fingerprint authentication based on the obtained fingerprint image and the mapped fingerprint image being identical with each other based on a result of the comparison.
