Abstract: Embodiments described herein include a method for detecting a presence of an input in a capacitive sensing device that includes a sensing region and a plurality of sensor electrodes. The method includes driving a first column of transmitter sensor electrodes at a first potential and driving a second column of transmitter sensor electrodes at a second potential different than the first potential. The method includes acquiring a measurement from each row of sensor electrodes, where a first sensing node includes the first column of transmitter sensor electrodes and a third column of receiver sensor electrodes, and a second sensing node includes the second column of transmitter sensor electrodes and a fourth column of receiver sensor electrodes. The method also includes determining, using the measurements from each row of sensor electrodes, a first set of transcapacitive measurements corresponding to the plurality of sensor electrodes.
