Abstract
This paper reports a new segment-mismatch-shaping technique for multi-bit ΔΣ DACs. Our technique allows an arbitrary weight of unit elements in each segment and a high (>; 2) segment mismatch shaping order. In addition, our required number of unit elements does not increase as the segment-mismatch-shaping order increases. Simulations under various conditions prove the validity of our technique.
