中文摘要：
基于延迟生成并合成窄脉冲方法,采用标准0.18μm CMOS工艺设计了一种3.1~10.6GHz全频段IRUWB发射机.通过对数据及时钟信号进行适当地延迟并用于控制脉冲形成单元电路,使其在不同的时钟沿产生对应于不同数据电平的0°和180°五阶高斯脉冲,实现BPSK调制及高斯脉冲同时产生的功能,从而有利于简化电路结构,降低功耗.版图后仿真实验结果表明：在电源电压为1V的情况下,输出脉冲峰-峰值为200mV,宽度为280ps,其功率谱密度符合FCC的UWB频谱规范;其最高数据率可达400 Mb/s,功耗仅为12.5pJ/b.
英文摘要：
In this paper,an IR-UWB transmitter that cover 3.1~10.6GHz frequency range is presented.It＇s based on the method that delay generating and synthesis pulses and designed with standard 0.18μm CMOS process.The transmitter realizes a function that BPSK modulation and 5th-order Gaussian derivative pulse generation simultaneously by delays the data and clock signal appropriately and uses them to control pulse-generation cell to generate 0°and 180°5th-order Gaussian derivative pulse corresponding to different data at different edge of clock.It is beneficial to simplify the circuit structure and reduce power dissipation.The post-layout simulation experiment result show that：when the supply voltage is 1V,the peak to peak voltage and width of output pulse is 200 mV and280ps respectively,its power spectrum density（PSD）comply with the FCC spectrum mask;the max data rate is400 Mb/s and the power dissipation is only 12.5pJ/b.
