摘要： Various embodiments in the disclosure provide methods implemented by a processor executing on a mobile communication device to dynamically determining whether the power saved by powering down the RF chain between the end of the last reception activities and the beginning of the next reception activities will exceed the power expended to reinitialize the RF chain's components and registers for the next reception activities. Based on this determination, the device processor may configure the RF chain either to power down fully, as in conventional implementations, or to enter a low-power mode in which power is maintained to the power rails supplying the memory registers storing RF communication data, thereby avoiding the power surge of restarting the registers and part of the power drain associated with writing the communication data back into the registers. In some embodiments, the mobile communication device may be a multi-SIM device.

摘要： A satellite positioning system (SPS) receiver that can provide good performance with low power consumption is described. The SPS receiver may be operated in one of multiple modes, which may be associated with different bias current settings for the SPS receiver. One of the modes may be selected based on output power level of a transmitter co-located with the SPS receiver. The bias current of an LNA, a mixer, and/or an LO generator within the SPS receiver may be set based on the selected mode. In one design, a first (e.g., lower power) mode may be selected for the SPS receiver if the transmitter output power level is below a switch point. A second (e.g., high linearity) mode may be selected if the transmitter output power level is above the switch point. The second mode is associated with more bias current for the SPS receiver than the first mode.

摘要翻译：描述了能够以低功耗提供良好性能的卫星定位系统（SPS）接收机。 SPS接收机可以以多种模式之一操作，这可以与SPS接收机的不同偏置电流设置相关联。可以基于与SPS接收机共处的发射机的输出功率电平来选择其中一种模式。可以基于所选择的模式来设置SPS接收机内的LNA，混频器和/或LO发生器的偏置电流。在一种设计中，如果发射机输出功率电平低于切换点，则可以为SPS接收机选择第一（例如较低功率）模式。如果发射机输出功率电平高于开关点，则可以选择第二（例如，高线性度）模式。与第一模式相比，第二模式与SPS接收机的偏置电流相关。
