Abstract
By virtue of its smaller bus, a nested bus-splitting DDSM has a potential speed advantage over its conventional counterpart. However, it can also suffer from poorer spur performance, especially in the case of constant and/or periodic inputs. By combining the features of nested bus-splitting and HK-MASH, a hybrid structure can retain the speed advantage… (More)
