摘要： An apparatus for reducing noise 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 analog front end is coupled to the fingerprint sensing area and is configured to generate an analog response signal. An analog-to-digital converter (ADC) samples the analog response signal and converts the sample to a digital value, which may be received by a digital device such as a processor or CPU. To reduce the amount of the noise that is present in the analog response signal and therefore reflected in the digital value, the digital device may be shut down while the ADC is sampling the analog response signal.

摘要： An apparatus for culling substantially redundant data in a fingerprint sensing circuit is disclosed in one embodiment of the invention as including an input module, a storage module, a comparator module, and a determination module. The input module may receive sets of data samples from an array of fingerprint sensing elements. The sets of data samples may be stored by the storage module. The comparator module may calculate a difference between each data sample from a first-received set, and a corresponding data sample from a second-received set. The determination module may count the number of difference values that exceed a predetermined difference limit, and identify the second set of data samples as redundant if the number of difference values counted is less than a pre-set count limit.

摘要： An apparatus and method for detecting the presence of a finger on a fingerprint sensor is disclosed in one embodiment of the invention as including transmitting a probing signal, comprising a series of probing pulses, to a fingerprint sensing area. A response signal, comprising a series of response pulses, is received from the fingerprint sensing area in response to the probing signal. An upper reference signal is generated and finger activity is detected on the fingerprint sensing area by monitoring whether the peaks of the response pulses exceed the reference signal.
