| Abstract: | This paper presents a design method for Wide-Band Signal Sampling (WBSS). Hybrid filter banks, unique clock distribution and multi phase storage are discussed for considering high precision, synchronized sampling and mass samples storage. Consequently, a design of WBSS based on above techniques is presented and its hardware prototype is realized with a 12 bit, 200 Msa/s for applications of WBSS. |
