Abstract
Techniques for correcting tail effect are described herein. In an example embodiment, a device comprises a sensor coupled with a processing logic. The sensor is configured to measure a plurality of measurements from a sensor array, where the measurements are representative of a conductive object that is in contact with or proximate to the sensor array. The sensor array comprises RX electrodes and TX electrodes that are interleaved without intersecting each other in a single layer on a substrate of the sensor array. The processing logic is configured to determine a set of adjustment values that correspond to a tail effect associated with the measurements, and to generate adjusted measurements based on the set of adjustment values, where the adjusted measurements correct a parasitic signal change of the tail effect.
