    Abstract: A magnetic shield for an inductor is disclosed that may substantially reduce unwanted magnetic coupling from other inductive circuitry. An inductive apparatus includes an inductor and a magnetic shield to shield the inductor from magnetic coupling effects. The magnetic shield includes an inductive ring formed from a plurality of turns surrounding the inductor. The magnetic shield may be used to reduce a magnetic coupling between the inductor and an inductive circuit element. Thus, the number of turns of the inductive ring may be based on the magnetic coupling between the inductor and the inductive circuit element. Further, a distance between the magnetic shield and the inductor may be based on the number of turns of the inductive ring. The distance between the magnetic shield and the inductor is to offset a magnetic coupling between the inductor and the magnetic shield.

    Abstract: A method and apparatus are disclosed for mitigating a frequency spur included with a transmitter output signal from a wireless device. For at least some embodiments, the wireless device may include an auxiliary synthesizer to generate a spur cancellation signal to be summed with the transmitter output signal to cancel or reduce the frequency spur. The auxiliary synthesizer may also generate an auxiliary clock signal to demodulate a received communication signal. In some embodiments, the transmitter output signal may be looped back to a receiver of the wireless device to determine whether the frequency spur is reduced below a threshold. Data from the receiver may be used to modify the spur cancellation signal.
