  • Frequency detect circuit for determining sample speed mode of decoded audio input data streams
    Patent number: 6556157
    Abstract: Disclosed is a data converter and a method for converting a digital audio stream representing an analog signal that has been sampled at a certain rate. The circuit includes a divider that receives a clock signal associated with the digital audio stream and divides the clock signal by a selectable division factor. The division factor is set according to divider control signals. At the output of the divider is provided an internal clock signal. A frequency detection circuit receives the signal from the output of the divider, and the frequency detection circuit detects the original sampling rate of the audio signal based upon intrinsic characteristics (e.g., MCLK to LRCK ratio) of the digital audio stream.

  • Common mode shift in downstream integrators of high order delta sigma modulators
    Patent number: 6369729
    Abstract: A technique for shifting a common mode voltage in a modulator comprised of a plurality of differential stages, so that downstream stages can use a lower voltage drive than the first stage of the modulator.
