ABSTRACT:
The management of unit element selections in a system that includes multiple unit elements. The system includes an element selection component that is configured so that each of the multiple elements is used the same number of times over a certain number of selection cycles. This preserves the first order noise shaping of the mismatch noise thereby keeping a high signal to noise ratio. In addition, the selection of the unit elements is not done in a periodic fashion. This allows the system to avoid tones within the signal band.
