Digital-to-analog converter data rate reduction by interleaving and recombination through mixer switching

摘要

A system and method implement very high data rate baseband DACs suitable for wireless applications related to new standards (e.g. Ultra-Wide Band) using CMOS processes allowing an integrated solution with the deep-submicron CMOS digital baseband. A single CMOS block working at full speed is discarded in favor of several blocks, each working at a fraction of the original data rate.
