Abstract
Techniques for eliminating 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 when the sensor array is in an unsettled state, where the measurements represent a conductive object that is proximate to a touch-sensing surface 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 plurality of measurements, and to generate adjusted measurements corresponding to the plurality of measurements based on the set of adjustment values.
