초록

In this paper, we propose a analog front-end (AFE) for noncoherent On-Off Keying (OOK) Ultra Wide Band (UWB) system based on power detection. The proposed AFE are designed using 0.18 micron CMOS technology and verified by simulation using SPICE. The proposed AFE consist of Sample-and-Hold block, Analog-to-Digital converter, synchronizer, delayed clock generator and impulse generator. The time resolution of 1ns is obtained with 100MHz system clocks and the synchronized 10-bit digital outputs are delivered to the baseband. The impulse generator produces 1ns width pulse using digital CMOS gates. The simulation results show the feasibility of the proposed UWB AFE systems.
