  • Modified first-order noise-shaping dynamic-element-matching technique
    Patent number: 8736476
    Abstract: A technique includes selectively enabling a first sequence of unit elements of a plurality of unit elements of a digital-to-analog converter to convert a digital code to a plurality of analog signals in response to a plurality of control signals. Individual control signals of the plurality of control signals and individual analog signals of the plurality of analog signals correspond to respective unit elements of the plurality of unit elements. The technique includes generating the plurality of control signals based on the digital code, a random digital code having a number of bits based on a feedback signal, and an indicator of a second sequence of unit elements of the plurality of unit elements enabled in response to a prior digital code.
