| 摘 要： | 本文给出了一种新颖的、全集成的、3-5GHz脉冲式超宽带发射机。发射机为BPSK调制模式，采用SMIC 0.13μm工艺流片，电源电压为1.2V，芯片总面积为0.8x0.95 mm2。基于脉冲式冲击响应滤波方法，发射机采用可调电阻R与选频网LC并联组成滤波网，实现脉冲带宽、长度和幅度参数连续可调。考虑脉冲式超宽带极低占空比的特点，本文提出的输出buffer大幅降低整体功耗。测试结果表明：发射机在100MHz的脉冲传输速率下，实现了16.3pJ/pulse的低功耗，同时所产生的脉冲完全符合FCC的频谱规定。脉冲长度从900ps-1.5ns连续可调，脉冲最小幅值为178mVpp，最大幅值为432mVpp.
