超宽带(UWB)技术是目前最先进且精准的短距离无线通信技术，基于窄脉冲的超宽带通信是最为经典的实现方式。本文通过分析现有的几种典型超宽带窄脉冲产生方法，分别从模拟电路和数字电路角度介绍了四种超宽带窄脉冲产生电路，给出了四种脉冲发生器的仿真结果，并从电路结构和性能方面进行了讨论和比较。
Ultra-wideband (UWB) technology is the most advanced and accurate short-range wireless com-munication technology at present. UWB communication based on narrow pulse is the most classical way to realize it. In this paper, by analyzing several typical UWB narrow pulse generation methods, four UWB narrow pulse generation circuits are introduced from the angle of analog circuit and digital circuit respectively. The simulation results of four pulse generators are given, and the circuit structure and performance are discussed and compared.
