  • Publication number: 20210225352
    Abstract: An integrated circuit for implementing at least a portion of a personal audio device may include an output for providing an output signal to a transducer, wherein the output signal includes a pilot signal, a microphone input for receiving a microphone signal from a microphone indicative of an output of the transducer, and a processing circuit. The processing circuit may be configured to implement a pilot signal control to apply an adjustment to the pilot signal as necessary to maintain the pilot signal at a substantially constant magnitude regardless of proximity of the transducer to a pinna and implement a proximity determination block configured to determine proximity of the transducer to the pinna based on the adjustment.
    Type: Application

  • Patent number: 9628088
    Abstract: Digital control of a crystal oscillator is implemented in a manner that allows frequency accuracy to be traded off dynamically with power consumption. The oscillator transitions between a less accurate/lower power mode and a high accuracy/higher power mode smoothly without requiring any external clock source during the transition. Power consumption is optimized because the crystal oscillator provides the clock source during transitions between the power modes and no other clock source is needed for these transitions. The system can also optimize the startup time and steady state power consumption independently.
