  • Coupled delta-sigma modulators
    Patent number: 7961129
    Abstract: An apparatus and method for reducing error in converting a multi-bit signal to a single bit signal. An analog delta-sigma modulator receives an analog signal and converts it to a multi-bit digital signal that is provided to a digital delta-sigma modulator. The digital delta-sigma modulator introduces error by converting the multi-bit signal to a single-bit signal. The error from the conversion is fed back to the analog delta-sigma modulator which incorporates the error information into the analog signal before it is converted to a multi-bit digital signal.
