本文提出了一种低功耗CMOS脉冲发生器的设计，基于脉冲超宽带应用。设计的基本结构包括一个变长矩形脉冲发生器、一个CMOS准高斯脉冲成形滤波器和一个小型微带天线模型。仿真结果表明，在0~960 MHz频段内，天线输出的脉冲符合FCC的频谱要求，在100 MHz脉冲重复频率下，功率消耗为234 μ W。用于创建脉冲发生器的CMOS电路非常简单，适合于低功耗、单芯片UWB发射机解决方案
The paper presents a low power CMOS pulse generator design for impulse based UWB applications. The basic structure of the design involves a variable length rectangle pulse generator, a CMOS quasi-Gaussian pulse shaping filter and a small monopole antenna model. Simulation results show the pulse after the antenna is compliant with the FCC's spectrum mask for 0~960 MHz band and has a power consumption of 234 muW at the pulse repetition frequency of 100 MHz. The CMOS circuit used to create the pulse generator is simple and lends itself to a low-power, single-chip UWB transmitter solution
