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- $mu text{m}$ CMOS process. The chip core area is 0.031 mm² for the transmitter and 0.017 mm² 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 $1.3times 10^{-3}$ bit error rate, 2.5Mb/s, and 10.42-ns pulsewidth is −60dBm.
