  • Ambient noise cancellation in pulsed input system
    Patent number: 8847578
    Abstract: Embodiments of the invention provide a pulseoximetry system with ambient offset cancellation that subtracts an estimated ambient offset to thereby allow a large front end gain while operating the front end on a low supply voltage. This large gain reduces input referred noise of an analog to digital converter in the front end while providing high dynamic range for signals with a large ambient offset.
    Type: Grant
    Filed: July 19, 2012
    Date of Patent: September 30, 2014
    Assignee: Texas Instruments Incorporated
    Inventors: Jagannathan Venkataraman, Sandeep Kesrimai Oswal, Vinod Srinivasan Paliakara
