    Abstract: A power management system that can include an application processor and a power management unit (PMU). The PMU can generate a regulated output voltage based on control signals generated by a switch control module of the application processor. The control signals can be determined based on a comparison of monitored voltages within the application processor and a generated reference voltage. The reference voltage can be generated based on fed back signals corresponding to the control signals. The application processor and the PMU can be formed utilizing different size manufacturing process technologies. For example, the PMU can be formed utilizing a larger size manufacturing process technology than the application processor.

    Abstract: A communication device includes a first and second near-field wireless (NFW) module operating with a first and second protocol, respectively. A module and method to improve the operational efficiency of the first and second NFW modules are disclosed. Due to close proximity between the first and second NFW modules in the communication device, an undesirable parasitic inductive coupling can occur that can degrade the operational performance of the modules. The first NFW module can be configured to control inductive coupling of the second NFW module when an electromagnetic (EM) field operating with the first protocol is detected. Additionally, the second NFW module can be configured to control inductive coupling of the first NFW module when an EM field operating with the second protocol is detected. Controlling the inductive coupling of each module can be performed by means of detuning an inductive coupling element of each module.

    Abstract: A wireless power transfer (WPT) station is disclosed for wirelessly transferring power to a WPT enabled device. To initiate charging of the WPT enabled device, the WPT enabled device is simply moved to be proximate to the WPT station. After an initialization and setup period, the WPT station transmits power transfer signals to the WPT enabled device. The WPT enabled device receives the transferred power transfer signals, typically through inductive coupling, and extracts a voltage and/or current therefrom for charging. The extracted voltage and/or current can then be rectified and/or regulated by the WPT enabled device to produce a charging voltage and/or charging current that can be stored in a power storage element, such as a battery or a capacitor to provide some examples, of the WPT enabled device.
