Abstract
A sensing device with a fingerprint sensor is provided. The sensing device includes a touch input pattern included in the fingerprint sensor, an oscillation circuit connected to the touch input pattern and configured to change a capacitance of the oscillation circuit when a touch occurrence is sensed by the touch input pattern and generate an oscillation signal based on the change in the capacitance, and an operation detection circuit configured to detect a touch occurrence based on a frequency included in the oscillation signal input from the oscillation circuit and generate a detection signal.
