Abstract
A method for removing component mismatch errors for a system parameter being set by a ratio of two or more physical, electrical components ('components') of the same kind on an integrated circuit including providing an array of component units having the same component value, determining the actual component values of each component unit in the array, selecting component units based on the actual component values to form pairs of component units where the pairs have approximately the same total component values, ordering the component unit pairs, assigning alternate component unit pairs to be associated with each of the two or more components, rotating at a first frequency the assignment of the component unit pairs. At each rotation, the component unit pairs to be associated with each component are shifted so that each component unit pair is associated with a different one of the two or more components in turn.
