“…Since the carrierless non-coherent UWB receiver has its wideband characteristics, in the actual channel the undesired outband interferers is also received and mixed, which in turn degrades the receiver sensitivity seriously. However, although many recent literatures report the UWB RF transceivers [1,2,3,4,5], only few reports address how the rejection of such interferers would be filtered and rejected. To our field experience, the undesired signals such as 2.4 GHz ISM band and WCDMA are most harmful noise for the 3 ～ 5 GHz UWB RF.…”

“…To our field experience, the undesired signals such as 2.4 GHz ISM band and WCDMA are most harmful noise for the 3 ～ 5 GHz UWB RF. Up to now, the several previous reports describe the integrated RF notch filter or its performance along with the interference [3,4,5]. However, the system performance improvement such as BER and the sensitivity including the interferer condition have not been scrutinized deeply in these literatures.…”

A fully integrated 3 ～ 5 GHz CMOS RF transceiver for IR-UWB applications is implemented in 0.18 m CMOS technology. The integrated RF notch filter is employed to reject the nearby WiFi and WCDMA interferers. The low power digital impulse generator is used as the UWB RF transmitter. The measured sensitivity of the receiver is À65 dBm at 4 GHz with 1 Mbps PRF. And the measured energy efficiency per pulse is 20.6 pJ/bit. The current consumption of the receiver and transmitter including DA is 27.5 mA and 25.5 mA, respectively, at 1.8 V supply.

“…Two recently reported examples of ULP radios shown in Fig. 1 are the wake-up receiver [1] and impulse-UWB transceiver [2]. The 2GHz wake-up receiver uses on/off keying (OOK) and envelope detection in a simple tuned-RF receiver to achieve -72dBm sensitivity, 50µW power consumption and throughput in the 10-100kbit/s range.…”

Two ultra low power wireless concepts are described in this paper. A high data rate receiver demonstrator consisting of LNA, subharmonic I/Q mixer and transimpedance IF amplifiers realizes an energy consumption of 1.75 nJ/bit at 10Mbit/s in the 17GHz band. A high-band FM-UWB receiver demonstrator, which achieves a measured sensitivity of -84.3dBm at 100kbit/s while consuming just 6mW is also described.

“…It is worth noting that, the authors are not the first ones who attempt applying frequency-domain approaches to UWB signal generation and reception. Sub-band analysis [60], [61] and bank of passive resonators [62] were investigated before to relieve the high sampling rate problem in UWB receivers; and, Fourier synthesis was suggested for UWB signal generators as early as in 1997 [63]. However, to the best of the authors' knowledge, the hardware architecture in this paper, which combines Fourier transform and inverse Fourier transform circuits to accomplish time-reversal of UWB signals, had never been reported.…”

Abstract-In this paper, a compact and low-cost electronic circuit system is designed for time-reversal of ultra-wideband short impulses (with nanosecond and sub-nanosecond temporal durations). A frequency-domain approach is adopted to avoid high sampling rate in time. Specifically, the proposed system obtains the discrete spectra of input impulses first; then realizes time-reversal in frequency domain; and finally synthesizes the time-reversed impulses using discrete continuous wave elements. This system is composed of common and commercially available circuits, and hence, can embody a system-on-chip implementation. Its performance is verified by circuit-electromagnetic co-simulations using impulses with 3-10-GHz frequency band coverage. Advanced Design System and two full-wave Maxwell's equations solvers are used for circuit and electromagnetic simulations, respectively, and their results are coupled and integrated. In the circuit part, most of nonidealities of realistic circuits are taken into account. It is shown by the simulation results that, although realistic circuits unavoidably introduce errors to time-reversal, such errors do not affect the "focusing" phenomena in the context of electromagnetic wave propagation. As a conclusion, the proposed system can be deployed in practical time-reversal communication and radar applications.Index Terms-Electronic circuit system, frequency-domain approach, short impulses, time reversal, ultra-wideband (UWB).
