  • Method and device for reducing radio frequency interference of proximity and touch detection in mobile devices
    Patent number: 10345963
    Abstract: A proximity sensor has a sensing node. A radio frequency signal is received at the sensing node. The radio frequency signal is coupled to an intermediate node through a first capacitor. The radio frequency signal is coupled from the intermediate node to a ground node through a second capacitor. An RF amplifier is coupled to the sensing node. The radio frequency signal is generated using the RF amplifier. A third capacitor is coupled between the RF amplifier and the sensing node. An antenna is coupled to the sensing node. The radio frequency signal is transmitted using the antenna. A capacitance of the antenna is measured using the proximity sensor. The capacitance of the antenna is compared to a threshold to determine proximity of a conductive object. An inductor is coupled between the sensing node and the antenna. A shielding area is coupled to the intermediate node.
