A UWB-IR (ultra wideband-impulse radio) receiver for simultaneous data communication and locationing based on the TDOA (Time Difference of Arrival) system is presented. Because the target measurement error of the locationing is 30 cm, a challenging issue of the system is to suppress the measurement error of a time interval within 1 ns. The proposed receiver includes an accurate time-interval-measurement...
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...
A 1-GHz input bandwidth 6-bit analog-to-digital (A/D) converter is described. The A/D converter is designed for an ultra-wideband impulse radio (UWB-IR) receiver that needs to digitize an input signal with a higher frequency than the sampling frequency. With the proposed under-sampling technique, sampling is executed with low-current consumption by separating a sampling capacitor from an operational...
A low power receiver analog front end (AFE) for ultra-wideband impulse radio (UWB-IR) 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 pulse repetition frequency of the received signals. Power consumption of the receiver AFE is decreased 60% by intermittent operation...
