摘要：
An apparatus for reducing power consumption in fingerprint-sensing circuits is disclosed in one embodiment of the invention as including a fingerprint sensing area onto which a user can apply a fingerprint. An integrated circuit communicates with the fingerprint sensing area and is configured to detect finger activity over the fingerprint sensing area. The integrated circuit includes a primary logic portion configured to assume control of the integrated circuit when finger activity is detected over the fingerprint sensing area. The integrated circuit also includes a secondary logic portion configured to assume control of the integrated circuit and shut off power to the primary logic portion when finger activity is not detected over the fingerprint sensing area.
