  • Method and system for detecting, and controlling power for, an auxiliary microphone
    Patent number: 8103022
    Abstract: Methods and systems for detecting, and controlling power for, an auxiliary microphone are disclosed. Aspects of one method may include a detection block intermittently enabling a bias circuit block to provide a bias signal to determine if an auxiliary microphone may be communicatively coupled to a mobile device. The detection block may process 1-bit digital samples received from the bias circuit bock to determine whether the auxiliary microphone may be communicatively coupled. The detection block may also process the 1-bit digital samples to determine if a button associated with the auxiliary microphone may have been pushed or activated.
