Abstract:
A device and system for automatically tracking a baseline input into a biometric sensor is provided. The device and system include a processing system with an amplifier having an input terminal and an output terminal for producing an output signal based on the input signal received by the input terminal. The processing system further includes at least one signal conditioning element coupled to the input terminal of the amplifier and configured to condition a compensation signal, and the processing system further includes a control circuit that adjusts one or more signal conditioning parameters of the at least one signal conditioning element based on the output signal of the amplifier. The at least one input signal received by the input terminal includes a combination of the at least one compensation signal and a signal from a first set of one or more receiver electrodes of the biometric sensor.

Claim (Index 13):
An electronic system for capacitive sensing, the electronic system comprising:\n a capacitive sensor configured to capacitively sense an input object in proximity to a plurality of electrodes, wherein the plurality of electrodes comprises: a first set of one or more transmitter electrodes capacitively coupled to a first set of one or more receiver electrodes and forming a first signal path for a first sensor input signal; and a second set of one or more transmitter electrodes capacitively coupled to a second set of one or more receiver electrodes and forming a second signal path for a second sensor input signal with opposite phase to the first sensor input signal; a processor configured for automatically tracking a baseline value of the first input signal and the second input signal, the processor comprising:\n a first compensation path including a first signal conditioning element, wherein the first compensation path transmits a first compensation signal; and \n a second compensation path including a second signal conditioning element, wherein the second compensation path transmits a second compensation signal with opposite phase to the first compensation signal; \n an amplifier including a first input terminal, a second input terminal and an output terminal, wherein the first sensor input signal and the first compensation signal are combined into a first amplifier input signal on the first input terminal and the second sensor input signal and the second compensation signal are combined into a second amplifier input signal on the second input terminal, and the output terminal produces an output signal based on the first amplifier input signal and the second amplifier input signal; and a control circuit providing a feedback signal to the first signal conditioning element and the second signal conditioning element and configured to adjust one or more signal conditioning parameters of the first signal conditioning element and the second signal conditioning element, wherein the feedback signal is derived from the output signal of the amplifier.
