  • Methods and apparatus for interference canceling data conversion
    Patent number: 8922401
    Abstract: Methods and apparatus for interference cancelling data conversion. In one embodiment, an input includes an interfering signal and a signal of interest. In one embodiment, a system extends the received signal dynamic range of an analog-to-digital conversion system by partially cancelling an interfering signal with multiple analog-to-digital converters, a digital-to-analog converter, a programmable delay block, a gain block, and a difference amplifier, inverse non-linear blocks, and digital signal processing to reconstruct the received signal in the digital domain.
