摘要:
A fingerprint sensing circuit for detecting a fingerprint of a user, including a signal source, at least a sensing unit, a resistor, an electrode, and a detecting circuit. The signal source provides a reference signal. The electrode is coupled to a reference level. The sensing unit generates a sensed value according to the electrode and the fingerprint of the user. The resistor is coupled between the signal source and the output node. The detecting circuit is coupled to the output node. The resistor, the sensing unit, and the electrode constitute a filter circuit to the signal source. At least a first signal is generated to the output node according to the reference signal and the sensed value, and the detecting circuit detects the first signal to generate a corresponding detected result indicative of the fingerprint.
