“…The comparisons of the obtained Figures of Merit with pulse generators performances found in literature [8]- [10] are summarized in Table I. Unfortunately, the post-layout simulation results for the same pulse repetition frequency (200 MHz) and the higher UWB sub-band in 0.18μm CMOS technology could not be found in the literature.…”

A new method of impulse radio ultra-wideband (IR-UWB) pulse generation is investigated in this paper. Low power pulse generator is composed of a glitch generator, a pulse oscillator, and a pulse shaping filter. The circuit presented was designed in a 0.18µm UMC CMOS technology. Since the impulse radio-based generator operates in burst mode with low duty cycle it has very low power consumption of 1.64 mW. This corresponds to energy consumption of 16.4 pJ per pulse considering 200 MHz pulse repetition frequency. Post-layout simulation results showed spectrum that fully complies with the corresponding FCC spectral mask. It has -10 dBm bandwidth of 5.7 GHz from 4.9 GHz to 10.6 GHz. The peak-to-peak amplitude was 180 mV on 50 Ω output load. The core design has size of 0.2 mm 2 . The pulse generator has been evaluated for the best performance supporting on-off keying modulation.

“…In an IR-UWB transmitter, most of the power is consumed in the electronics that generate the pulse rather than in the PA. Implementations of pulse generators can be analog, based on derivatives [45], on multipliers [29,[46][47], on filters, or, more recently, on oscillators which produce the UWB pulse based on startup/fall-down time [48][49][50][51]. Digital implementations have also been used, which rely on multiphase ring oscillators and/or a combination of different path delays [52][53][54][55][56][57][58][59] to produce the wanted pulses. All-digital transceivers can take the maximum advantage of CMOS technology scaling.…”

Modern Ultra-Wide Band (UWB) regulations have recently been adopted worldwide allowing for unlicensed operation within 3.1 and 10.6 GHz, using an appropriate wideband signal format with a low Effective Isotropic Radiated Power (EIRP) level. UWB characteristics are suitable to transmit data using pulses instead of continuous-waves such as in narrowband radio links. It has the potential to be the right technology for high data-rate, low-power and short-to-medium range communication systems.We will focus on Impulse Radio-UWB (IR-UWB) systems and show their suitability for many different applications, including sensor networks, ad-hoc networks, cognitive radio, home networking, etc. We will also discuss the difficulties and challenges of designing IR-UWB systems. We present a tutorial overview of UWB regulations and usable signals.We present the existing standards and recommendations, and we review recently published results, highlighting trends in UWB transceiver power consumption and the impact of CMOS scaling on performance.

This paper presents a detailed analysis, design and simulation of pulse generator for Ultra-Wideband (UWB) based on LC-tank differential oscillators topology. The differential oscillators with a cross-coupled NMOS pair and a tail current source are used to achieve more positive gain and generate negative resistance to the LC-tank. Besides, this oscillator is suitable for UWB high frequency and low power applications. The UWB pulse generator is composed of a simple on-off keying (OOK) modulated and LC-tank differential oscillators. The circuit of UWB pulse generator designed and simulated in 0.13 um CMOS technology. The UWB pulse generator generates a pulse for the 6 - 10 GHz UWB transmitter. Simulation results show a pulse width of 586 ps, a peak to peak amplitude pulse of 88.6 mV from the 1.2 V power supply and the die area of 0.22 mm2. The average power consumption of approximately 0.55 mW and an energy consumption of 1.1 pJ/pulse at 500 MHz pulse repetition rate (PRR) are observed.
