这封信报告了一个集成的超宽带脉冲无线电设计。该无线电采用频移键控和开关键控相结合的方式实现固有的时钟和数据恢复以及异步无线通信。发射机采用跳频和占空比方法来实现超宽带宽。发射机和接收机均采用IBM 0.18 μ m CMOS工艺制作.发射器的芯片核心面积为0.031 mm（2），接收器的芯片核心面积为0.017 mm（2）。在3 Mb/s数据速率下，发射机功耗为2.89mW，接收机功耗为5.4mW。在误码率为1.3 × 10 ~（-3）、脉宽为10.42ns、速率为2.5Mb/s时，灵敏度为-60dBm。
This letter reports an integrated ultrawideband impulse radio design. The proposed radio applies a combination of frequency-shift keying and ON-OFF keying to realize intrinsic clock and data recovery as well as asynchronous wireless communication. The transmitter uses frequency-hopping and duty-cycling methods to achieve ultrawide bandwidth. Both of the transmitter and the receiver are fabricated on IBM 0.18-mu m CMOS process. The chip core area is 0.031 mm(2) for the transmitter and 0.017 mm(2) for the receiver. The measured power consumption is 2.89mW for the transmitter and 5.4mW for the receiver at the data rate of 3Mb/s. The sensitivity at 1.3 x10(-3) bit error rate, 2.5Mb/s, and 10.42-ns pulsewidth is -60dBm.
