    Abstract: A finger biometric sensor may include an array of finger biometric sensing pixels and processing circuitry coupled thereto. The processing circuitry may be capable of acquiring initial data from the array based upon an initial drive signal level and with a finger positioned adjacent the array, and determining an updated drive signal level based upon the initial data. The processing circuitry may also be capable of acquiring finger biometric data from the array of finger biometric sensing pixels based upon the updated drive signal level and with the finger positioned adjacent the array.

    Abstract: A finger sensor may include pixels, pixel sensing traces each associated with a respective pixel, and electrodes overlying the pixel sensing traces. The finger sensor may also include pixel sensing circuitry coupled to the pixel sensing traces and the electrodes. The pixel sensing circuitry may be capable of operating in a measurement mode by operating the pixels so that at least some of the pixels are active, and at least some other of the pixels are inactive and coupling pixel sensing traces associated with the inactive pixels to a voltage reference. The pixel sensing circuitry may also be capable of operating in the measurement mode by coupling electrodes associated with the active pixels to the voltage reference and coupling electrodes associated with the inactive pixels to a drive signal.

    Abstract: A finger biometric sensor may include a lower conductive layer, an upper conductive layer, and a spacer between the lower and upper conductive layers to define an air gap therebetween. The finger biometric sensor may also include a finger biometric sensing integrated circuit (IC) above the upper conductive layer and capable of deflecting the upper conductive layer toward the lower conductive layer to change a capacitance thereof based upon pressure applied to the finger biometric sensing IC. A pressure sensing circuit may be coupled to the lower and upper conductive layers to sense the change in capacitance.
