Abstract: Aspects of the subject disclosure may include, for example, a power receiving unit having a wireless power receiver configured to receive a wireless power signal from a power transmitting unit. A rectifier includes a plurality of switching circuits configured to generate a rectified voltage from the wireless power signal, based on switch control signals that include a switch-on signal and a switch-off signal for corresponding ones of the plurality of switching circuits. A rectifier control circuit generates the switch control signals based on predicted switching delays. Other embodiments are disclosed.

Abstract: A circuit includes a switching regulator that produces a first voltage supply output and that includes an operational supply input. The operational supply input may provide power for running the logic in the switching regulator. The circuit also includes a linear regulator that produces a second voltage supply output. A control circuit accepts the first voltage supply output and the second voltage supply output and includes a power output connected to the operational supply input. The control circuit is configured to pass the second voltage supply output to the power output until the first voltage supply output is established. After the first voltage supply is established, the control circuit instead passes the first voltage supply output to the power output through the control circuit. The first voltage supply output may also then provide power to the circuitry that would otherwise have been powered by the linear regulator.

Abstract: A power management unit accurately measures and controls charging current. The power management unit may be implemented more efficiently than prior designs, leading to cost savings in the implementation of the power management unit as well as in the implementation of the device that incorporates the power management unit. The power management unit incorporates a model of an external charge control device (e.g., a transistor) and uses that model in a way that allows the power management unit to eliminate external device pins and other circuitry.
