Moreover, the input device includes routing traces that electrically couple the sensor electrodes to analog front ends (AFEs). Because of the spatial relationships between these electrical components, the sensor electrodes can be categorized into groups where each of the sensors in the group is affected by a common noise source. The capacitive measurements for the sensor electrodes in each of the groups are compared to a touch threshold to determine if an input object (e.g., finger or stylus) is proximate to the sensor electrodes. If the capacitive measurements are below the touch threshold, the input device calculates an offset value that compensates for the noise. After the offset is applied, the compensated capacitive measurements are used to generate a capacitive image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mitigating spatially correlated noise in data from capacitive sensors","description":"This disclosure generally provides an input device with a matrix sensor that includes a plurality of sensor electrodes arranged on a common surface or plane.
