“…UWB signals are spread over large frequency bands with very low power spectral density. Such large bandwidths offer specific advantages with respect to signal robustness, information transfer speed, and/or implementation simplicity . The popularity of UWB—besides its technical particularities—stems from the fact that they can be used as an overlay to existing systems and allow unlicensed operation, provided UWB emission standards are met .…”

An experimental demonstration of 2.5 Gbit/s real‐time ultra‐wideband transmission is presented, using a Schottky diode‐based envelope detector fabricated ad‐hoc using microstrip technology on a Rogers6002 substrate and surface‐mount components. Real‐time transmission with a BER below FEC threshold is achieved for 20 cm of wireless transmission at 2.5 Gbit/s and 50 cm at 1.25 Gbit/s. © 2016 Wiley Periodicals, Inc.

“…UWB system is defined by Federal Communications Commission (FCC) and it is characterized by bandwidth superior to 1.5 GHz and Power Spectral Density (PSD) of -41.3 dBm/MHz [9]. Due to these strict constraints different architectures of UWB transmitter and receiver have been proposed in recent publications [1][2][3][4][5][6][7][8][10][11][12][13][14]. The band width of UWB communication is depicted in Fig.…”

In this paper a new design of Ultra-Wide Band (UWB) generator is presented. This circuit is the most important block in multi-bands transmitter architecture of UWB communication system. The proposed UWB generator is composed of multi-bands voltage controlled oscillator (VCO), mixer and rectangular pulse generator which consist of ring oscillator, time delay and AND gate function. The UWB generator is based on multiplying the rectangular pulse envelope to a continuous sinusoidal wave in order to generate the UWB signal. This UWB generator circuit produces an output signal which is characterized by the bandwidth of 1600 MHz divided into three sub-bands of 528 MHz, centered at frequencies of 3.432, 3.96, 4.488 GHz and the limited Power Spectral Density (PSD) is -41.44 dBm/MHz. The maximum amplitude of UWB signal is 214 mV, the pulse is during of 3 ns and the pulse repetition period (PRP) is 32 ns. The power consumption is approximately equal to 26 mW at a voltage supply of 2.5 V. This topology is designed in CMOS 0.35 lm AMS process technology.

“…For example, recent developments in UWB standards have proposed to exploit OFDM (orthogonal frequency division multiplexing), IR (impulse radio), and TR (transmit-reference) modulation techniques. Among them, IR-UWB is suitable for low rate applications (e.g., sensor network) and OFDM-UWB is more appropriate for high data rate transmission [4].…”

High-Gain Power-Efficient Front- and Back-End Designs for a 90 nm Transmit-Reference Receiver

A new microwave receiver configuration which transmits reference pulses embedded in data streams for synchronization is analyzed with a 90-nm IBM CMOS standard. A two-stage cascode low-noise amplifier (LNA) is proposed for the receiver front-end which is matched by a passive network to save on power-expensive matching techniques. The amplifier exploits a double-differential topology and achieves a below 4 dB noise figure near the center frequency. The overall 3-dB bandwidth is 3.3 GHz with peaking up to 20.5 dB in the -band. The back-end of the receiver is implemented through an adjustable analog window-detection circuit. It avoids the use of control voltage generators and sample-hold (S/H) blocks to save electronic overhead and is simulated with a 0.1~2.0 Gbps pulse stream. The achieved speed-to-power ratio for the back-end has a maximum limit of 266 GHz/W. When compared against simulated results of published literature, the proposed designs show improved performance in terms of small-signal gain, noise, speed, and power dissipation.
