摘要： A fingerprint sensor includes an array of fingerprint sensing elements; analog-to-digital (A/D) converters having a controllable range; a scanner to perform sequential A/D conversions of predetermined ones of the array of fingerprint sensing elements; and a range determining and setting circuit for controlling the range of the A/D converters based upon prior A/D conversions to thereby provide enhanced conversion resolution. A plurality of A/D converters are preferably used for simultaneously converting analog signals from a corresponding plurality of fingerprint sensing elements. The A/D converters may include at least one reference voltage input for permitting setting of first and second points of the range. The range scale determining and setting circuit may generate a histogram based upon prior A/D conversions. In addition, the range scale determining and setting circuit may set a default range for initial ones of the fingerprint sensing elements.

摘要： A fingerprint sensor includes a plurality of semiconductor devices adjacent a substrate and defining active circuit portions, and having only three metal layers. More particularly, the sensor may include a first metal layer interconnecting predetermined ones of the plurality of semiconductor devices; a second metal layer defining a ground plane; and a third metal layer comprising an array of electric field sensing electrodes connected to active circuit portions for generating an output related to a sensed fingerprint. The fingerprint sensor may also include a package surrounding the substrate and having an opening aligned with the sensing electrodes. In addition, a first external electrode may be carried by the package for contact by a finger. The sensor may thus also include an excitation drive circuit connected between the ground plane and the first external electrode for generating electric fields between the electric field sensing electrodes and adjacent finger portions. A power control circuit is for controlling operation of active circuit portions based upon sensing finger contact with the first external electrode so that the active circuit portions are powered upon sensing finger contact with the first external electrode and otherwise grounded. A second external electrode may be connected to a bleed resistor to bleed charge from the finger prior to switching from the grounded to the powered state. An amplifier connected between each electric field sensing electrode and associated shield electrode may be operated at a gain of greater than one for additional noise rejection.

The first portion is within the housing and mounts the fingerprint sensing integrated circuit, and the second portion is flexible and extends outwardly from the housing for facilitating electrical connection to the fingerprint sensing integrated circuit from external to the housing. Each portion of the circuit substrate preferably includes at least one insulating layer and at least one electrical conductor thereon. Accordingly, the package can be made relatively compact and electrical interconnections are facilitated by the second portion or extension of the circuit substrate. In one embodiment, the first and second portions are integrally formed together. In this embodiment, the first portion is also flexible. The sensor package is readily included on the upper surface of a laptop computer, for example.
