  • Capacitive touch device, capacitive communication device and communication system
    Patent number: 9389742
    Abstract: There is provided a capacitive touch device including a touch panel, a detection circuit and a processing unit. The touch panel includes a plurality of drive electrodes and a plurality of receiving electrodes configured to form a coupling electric field with an external touch panel, and the receiving electrodes are respectively configured to output a detection signal. The detection circuit is coupled to one of the receiving electrodes and configured to modulate the detection signal with two signals to generate two detection components. The processing unit is configured to obtain a phase value according to the two detection components to accordingly decode transmission data.
    Type: Grant
