Parasitic circuit for device protection |
摘要 |
Exemplary embodiments are directed to a device include a parasitic coil for protection of the device. A device may include a first circuit configured to receive a first transmitted signal at an operational frequency. The device may also include a second circuit a second circuit configured to generate a field that opposes at least one of an undesirable portion of a wireless power field of the first transmitted signal and a portion of another wireless power field proximate the first circuit, the another wireless power field generated by a second transmitted signal at a non-operational frequency of the first circuit. |

1. A device for protecting circuitry, comprising:
a first circuit configured to receive a first transmitted signal from a first transmitter at an operational frequency; and a second circuit configured to generate a magnetic field that opposes at least a portion of another magnetic field generated by a second transmitter at a frequency that is different from the operational frequency of the first circuit, wherein the second circuit is further configured to exhibit a first impedance in response to the operational frequency and exhibit a second impedance in response to the frequency that is different from the operational frequency. |
