A low power ultra-wideband impulse radio (UWB-IR) receiver was developed in 0.18-mum CMOS. All circuits of the receiver AFE operate intermittently with a sampling clock of an analog-digital converter (ADC). The sampling rate of the ADC is equal to the pulse repetition frequency of the received signals. Power consumption of the receiver AFE is reduced by 60% using a developed intermittent operation scheme without degrading of receiver sensitivity. As a result, the power consumption of the receiver AFE is 38 mW. The receiver has a data rate of 258 kb/s over a distance of 52 m and of 10.7 Mb/s over a distance of 14 m.
