摘要： Embodiments of this disclosure include methods in which spurs generated by the drifting of an oscillation frequency of an oscillation signal provided by a free-running oscillator may be minimized and/or eliminated from an output signal of a phase locked loop (PLL). Methods include minimizing the mixing gain between the oscillation signal and a power signal provided to the PLL. The oscillation signal and the power signal may be mixed in a phase frequency detector (PFD) included in the PLL. The minimizing of the mixing gain for the PFD also minimizes the degrading effect that the spurs have on the overall performance of the communications device. The mixing gain may be minimized by minimizing the impedance provided at nodes included in the PFD where the oscillation signal and the power signal mix. The mixing gain may also be minimized by maximizing the power supply rejection ratio for the PFD.

摘要： Systems and methods are described for controlling a reference oscillator shared by multiple subsystems of a communications system and arbitrating usage of the reference oscillator among these subsystems. By changing the properties of the reference oscillator (e.g., by tuning the reference oscillator) according to the needs of particular subsystem(s), the communications system can configure the reference oscillator to meet the specification requirements of these particular subsystem(s) and can later reconfigure the reference oscillator to meet the needs of other subsystems. Further, the controller can configure the subsystems based on parameters that impact multiple subsystems (e.g., by implementing geographic awareness, spectrum occupation awareness, and availability of Assisted GPS (AGPS) functionality) to achieve further optimization of the communications system.

摘要： Embodiments of the present disclosure can be used to both reduce the size and cost and improve the performance and power consumption of next generation wireless communication devices. In particular, embodiments enable board and semiconductor substrate area savings by using the fabrication package (which encapsulates the semiconductor substrate) as a design element in the design of next generation wireless communication devices. Specifically, embodiments use the substrate of the fabrication package to integrate into it components of the wireless radio transceiver (which are conventionally integrated into the semiconductor substrate) and other discrete components of the communication device (which are conventionally placed on the board of the device). As such, reduced board and semiconductor area can be realized.
