Abstract: A method of generating asynchronous feedback information for asynchronous, isochronous audio communication may include determining a relative change of stored samples in a device and generating the asynchronous feedback information provided to a host from the device based on the relative change. A method of generating asynchronous feedback information for asynchronous, isochronous audio communication may include determining a relative phase of a host clock for a host and a device clock for a device and generating the asynchronous feedback information provided to the host from the device based on the relative phase.

Abstract: An amplifier, electronic display system, and a related method for generating a low power signal with an operational amplifier are disclosed herein. An embodiment of the present invention includes an amplifier, comprising an operational amplifier and a voltage converter. The operational amplifier includes an inverting input, a non-inverting input, an output, a first power supply input and a second power supply input, and is configured to generate an output signal in response to an input signal. The voltage is operably coupled with the first power supply input of the operating amplifier, and is configured to receive a first supply voltage and generate a second supply voltage to the first power supply input of the operational amplifier. The voltage of the second supply voltage is relatively closer to the expected operating voltage range of the output signal than is the first supply voltage.
