双非门结构皮秒级窄脉冲设计∗
Design of Picosecond Short Pulse Based on Dual NOT Gates Structure
摘要
Abstract
Narrow pulse generation is a key technology in Ultra-wideband communication systems,and different ap-plications have different requirements for pulse generation. This paper analyzes several conventional Ultra-wideband narrow pulse generation methods in Ultra-wideband indoor positioning system. Their advantages,disadvantages and the existing problems are discussed. On this basis, a pulse generator is designed based on digital method firstly. Then propose a novel Ultra-wideband narrow pulse generation method which based on dual NOR gates structure by analyzing the simulation results of the designed pulse generator. The simulation results show that pulse repetition fre-quency obtained by using the method is 10 MHz,and the duration time is 150 ps. The experimental circuit test re-sults are basically consistent with the theoretical analysis and simulation results. Compared with the conventional narrow pulse generation method of digital circuit,this method is simple,low cost and the requirement is not high to the devices. Moreover,the obtained pulse width is narrower than dozen times and higher positioning accuracy.关键词
