“…UWB pulse generators can be broadly classified into two depending on the use of an up-conversion unit 19 . The ones that employ an up-conversion unit first generate a pulse at baseband, and then translate the frequency contents of the signal (i.e., "up-convert" it) around a desired center frequency [83]- [85]. On the other hand, some UWB pulse generators can directly generate the pulses in the desired frequency band without employing any up-conversion unit.…”

The high time resolution of ultra-wideband (UWB) signals facilitates very precise position estimation in many scenarios, which makes a variety applications possible. This paper reviews the problem of position estimation in UWB systems, beginning with an overview of the basic structure of UWB signals and their positioning applications. This overview is followed by a discussion of various position estimation techniques, with an emphasis on time-based approaches, which are particularly suitable for UWB positioning systems. Practical issues arising in UWB signal design and hardware implementation are also discussed.

This paper presents a novel CMOS impulse radio (IR) ultra-wide-band (UWB) transceiver system design for future contact-less chip testing applications using inductive magnetic coupling as wireless interconnect. The proposed architecture is composed of a simple and robust design of a Gaussian Monocycle impulse generator at the transmitter, a wideband short-range on-chip transformer for data transmission, and a -boosted commongate low-noise amplifier in the UWB receiver path. SpectreRF postlayout simulation with a 90-nm CMOS technology shows that the transceiver operates up to a 5 Gb/s data rate, and consumes a total of 9 mW under a 1-V power supply.Index Terms-CMOS, impulse radio (IR), ultra-wide-band (UWB), wireless interconnect, on-off keying (OOK).

“…The transistor based implementation [3] requires stable voltage and current sources. The realizations based on digital circuits lead to more complex circuits and are not suitable for low power applications [4][5][6][7][8][9][10][11][12][13]. In those methods, the generated pulses are not matched to the FCC mask and an additional filtering stage is needed.…”

This paper describes a simple and original method to generate short UWB pulses, obtained by the transient response of a notch filter. Whose the first principle is based on a technique On-Off Keying signal with a carrier frequency centered at the rejection frequency (requires a very fast switch and a sinusoidal carrier). Now, we propose an all-digital solution, using a Phase-Shift Keying modulation to produce short pulses. We compare the both methods and show that pulses with a spectrum satisfying the FCC indoor regulatory mask in USA. The second method (without fast switch) which can be applied to the generation of pulses matched to any type of available spectrum mask (European, Asia, imaging, medical, outdoor, radar, …). In both cases, circuits are realized at FCC to demonstrate these principles. It is shown that the measurements are in good agreement with the theory.
