  • Active charge through of a peripheral device
    Patent number: 10579119
    Abstract: A method for port policy management for active charge through of a peripheral device that has a first communication port and a second communication port may include detecting whether a valid power connection exists at the peripheral device, in response to detecting the valid power connection, determining a relationship between the first communication port and the second communication port, based on the relationship, determining, by the peripheral device, a power relationship among the peripheral device, the first communication port, and the second communication port, selectively configuring the first communication port, the second communication port, and the peripheral device to match the power relationship, and enabling active charging through of the peripheral device if active charging through is supported by the power relationship.

  • Transmit digital to analog converter (DAC) spur attenuation
    Patent number: 9379727
    Abstract: A method and apparatus for attenuating transmit digital to analog converter (DAC) spurs is provided. The method begins when a reference voltage is injected into an amplifier. Next, an output of the ground low drop-out regulator is measured and is them compared with the reference voltage. The output of the amplifier is then adjusted based on the results of the comparison. If the reference voltage is higher then the output of the ground low drop-out regulator the output of the amplifier is adjusted to ground. If the reference voltage is lower than the output of the ground low drop-out regulator then the output of the amplifier is adjusted to match the reference voltage.
