  • Patent number: 5126742
    Abstract: An analog to digital converter (ADC) is disclosed having a coarse converter to generate the most significant bits of the output and double folding interpolation circuitry to generate the least significant bits. Each side of the double folding circuit includes additional folding stages coupled to reference voltages above and below the full scale input range of the ADC to cancel offset errors and improve circuit linearity. The interpolation circuit includes one interpolation stage, having two multiplier networks, for each least significant bit. Each interpolation stage receives two pairs of signals from the preceding stage and outputs two pairs of signals to the next stage. One of the pairs of output signals from each interpolation stage is also sent to a latched comparator. The outputs of all of the latched comparators can be read directly as the ADC output bits without requiring a decoder.
