  • Systems and methods for controlling powerstage supply modulation via audio interface
    Patent number: 11917378
    Abstract: Systems and methods increase power efficiency in communication systems by examining a digital signal to determine whether a threshold corresponding to an increase in a power requirement is likely to be exceeded. The signal is encoded with information indicating the likely change and communicated to a driver that, upon extracting the information, uses it to cause instruct an amplifier to increase a power output to accommodate the increase in power requirement. Once the threshold is no longer exceeded, the driver circuit, advantageously, decreases the power output to conserve energy. In various embodiments, an amplifier may increase power efficiency by switching from a low-power circuit configuration to a high-circuit configuration.
