High-speed high-resolution DA converters are essential blocks in all kinds of mixed signal systems. Because of the development of technique of computer science, telecommunication and multimedia, the DA converters change rapidly in technique, construction and performance. The aim is low power dissipation, high speed and high resolution. This paper addresses using segment structure to improve the glitch performance based on the design issue of a 14bit segment DA converter.
