Abstract: PROBLEM TO BE SOLVED: To provide a device that adjusts the bias current of a satellite positioning system (SPS) receiver. SOLUTION: The SPS receiver operates in one of multiple modes for the SPS receiver associated with a plurality of different bias current settings for the SPS receiver. One of the multiple modes is selected based on the output power level of a transmitter apposed with the SPS receiver. The bias current of an LNA, a mixer, and/or an LO generator within the SPS receiver is set based on the selected mode. In one design, a first (e.g., lower power) mode is selected for the SPS receiver if the transmitter output power level is below a switch point. A second (e.g., high linearity) mode is selected if the transmitter output power level is above the switch point. The second mode is associated with a bias current of the SPS receiver, which is bigger than that in the first mode. COPYRIGHT: (C)2011,JPO&INPIT

解决方案：SPS接收机以与SPS接收机的多个不同偏置电流设置相关联的SPS接收机的多种模式之一工作。 基于与SPS接收机一起的发射机的输出功率电平来选择多种模式之一。 基于选择的模式来设置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，则选择第二（例如，高线性度）模式。 第二模式与SPS接收机的偏置电流相关联，其大于第一模式中的偏置电流。 版权所有（C）2011，JPO＆INPIT

Abstract: System(s) and method(s) are provided for dynamically scaling switching frequencies and clock sources of switched mode power supplies (SMPSs) in a mobile station. Switching frequency is scaled to an optimal value in response to at least one of (i) a change in mode of operation for wireless communication employed by the mobile station, an additional mode of operation is triggered, (ii) a change in operation conditions of a set of loads associated with functionality of the mobile is determined, or (iii) an LO spur set-off by a SMPS in the presence of an interference signal with a frequency splitting from an operational band that matches the SMPS frequency or at least one of its harmonics. Switching frequencies can be selected from a lookup table, or through an analysis of switching frequencies available to the mobile and operational criteria. A set of clock sources can provide an ensemble of switching frequencies.

Abstract: A satellite positioning system (SPS) receiver that can provide good perfo rmance with low power consumption is described. The SPS receiver may be oper ated in one of multiple modes, which may be associated with different bias c urrent 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. Th e bias current of an LNA, a mixer, and/or an LO generator within the SPS rec eiver may be set based on the selected mode. In one design, a first (e.g., l ower power) mode may be selected for the SPS receiver if the transmitter out put power level is below a switch point. A second (e.g., high linearity) mod e 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 rece iver than the first mode.
