    Abstract: This disclosure generally provides an input device that includes a plurality of sensor modules coupled to sensor electrodes arranged in a matrix that measure capacitive sensing signals corresponding to the electrodes. To mitigate the effect of capacitive coupling between a sensor electrode being sensed and its neighbors in the matrix, the input device drives the neighboring electrodes in a same manner as the selected sensor electrode so that there is little or no voltage difference between the sensor electrode being sensed and its neighbors. For example, during a drive phase, the electrode being sensed and the neighboring electrodes are coupled to the same charge voltage. During a read phase, the neighboring electrodes and the selected electrode may be coupled to the same reference voltage—e.g., ground—so there is again no voltage difference between the electrodes.

    Abstract: Embodiments herein describe an input device that includes a rectangular array of sensor electrodes connected to sensor modules that measure capacitive sensing signals corresponding to the electrodes. When performing code division multiplexing (CDM), multiple sensor electrodes are coupled to the same sensor module. As such, the sensor module generates a measurement that represents the sum of the charges on the sensor electrodes rather than an individual charge on a single sensor electrode. By repeatedly sensing multiple sensor electrodes in parallel, the input device can determine a change of capacitance for each individual sensor electrode.
