  • Patent number: 6522277
    Abstract: A circuit, system, and method are provided for imparting improved randomness into the selection of components or elements of a data converter, such as a D/A converter. The elements are intended to be of equal value, however, regardless of whether they are or not. A circuit is used to randomly select subsets of elements according to a bi-directional selection technique in order to effectively rending the elements or components of equal value. Associated with each component is a switch, and a subset of the plurality of components are correspondingly switched in successive order progressing in a first direction and, subsequently, in successive order progressing in a second direction opposite the first direction. Connecting components in a first direction from left-to-right follows by selecting components in a second direction from right-to-left, and then again selecting components in the first direction from left-to-right, and so forth.
