Abstract: Capacitive sensing includes concurrently driving a first transmitter electrode with a first transmitter signal and a second transmitter electrode with a second transmitter signal. The first transmitter signal is based on a first digital code and the second transmitter signal is based on a second digital code. The first digital code and the second digital code each include at least one non-integer multiple. Capacitive sensing further includes receiving resulting signals using multiple receiver electrodes, the resulting signals include effects of the first transmitter signal and the second transmitter signal. Capacitive sensing further includes determining positional information based on the resulting signals.

Abstract: In a method of input object sensing, a plurality of transmitter electrodes are driven in a first way to acquire a first sub-frame image with the plurality of transmitter electrodes and a plurality of receiver electrodes of a sensor electrode pattern during a first sub-frame of a transcapacitive sensing frame. The plurality of transmitter electrodes is also driven in a second way to acquire a second sub-frame image with the plurality of transmitter electrodes and the plurality of receiver electrodes during a second sub-frame of the transcapacitive sensing frame, wherein the first way and the second way differ. A capacitive image is determined by combining the first sub-frame image with the second sub-frame image such that a motion artifact associated with an input object and present in at least one of the sub-frame images is suppressed by the combining.

Abstract: A semiconductor device comprises first mixer circuitry and processing circuitry. The first mixer circuitry is configured to generate a plurality of first mixer outputs through quadrature decomposition of a sensing signal. The first sensing signal corresponds to a capacitance of a first sensing electrode supplied with a drive signal. The quadrature decomposition is based on an in-phase local carrier which is in phase with the drive signal and an out-of-phase local carrier having a phase different from that of the in-phase local carrier. The plurality of first mixer outputs comprises an in-phase mixer output generated based on the in-phase local carrier and the sensing signal, and an out-of-phase mixer output generated based on the out-of-phase local carrier and the sensing signal.
