Abstract
Apparatuses and methods of driving different transmit (TX) phase sequences of a TX signal on TX electrodes in different sensing stages according to a weighting matrix as the excitation matrix. One method drives the TX signals according to the weighting matrix and measures receive (RX) signals on the RX electrodes to determine if an object is proximate to the electrodes.
