  • Patent number: 11081778
    Abstract: A method and apparatus for performing a low-power presence check are provided. In the method and apparatus, a controller detects a presence of a tag by at least causing the antenna to generate a magnetic field over a first time period for detecting the tag, measuring an antenna voltage over a second time period, causing the antenna to cease generating a magnetic field over a third time period longer than the first time period and comparing the antenna voltage to an antenna reference voltage to determine whether the tag is present. The controller detects the presence of the tag in response to receiving a command from a host device for performing the low-power presence check. The command may be a one-time command for every presence check stage or a command that is repeatedly received each time the controller detects the presence of the tag.

  • Patent number: 10997483
    Abstract: Circuits and methods of operating multiple antennas using a shared controller are provided. In one embodiment, a method includes coupling, in a first configuration, a first antenna to the shared controller and decoupling a second antenna from the shared controller. The first antenna is coupled to the shared controller using a first matching circuit and a first filter. The method further includes operating a controllable activation component to define a second configuration state formed by decoupling the first antenna from the shared controller and coupling the second antenna to the shared controller. In this embodiment, the second antenna is coupled to the shared controller using a second matching circuit and a second filter. At least one capacitor of the first matching circuit is used in the second filter and at least one capacitor of the second matching circuit is used in the first filter.
