Abstract:
Apparatus and methods disclosed herein operate to reducing switching artifacts associated with dynamic element matching by sorting a set of unit elements to establish a priority order of selection of a subset of the set of unit elements to use in a next single-sample integration operation. Sorting is achieved by demoting unit elements during the sorting if a usage value associated with the unit element is greater than or equal to a maximum allowable usage spread parameter value. A unit element is promoted during the sorting if a usage value associated with the unit element is less than the maximum allowable usage spread parameter value and the unit element was used in an immediately previous single-sample integration operation.
