“…Even though the energy efficiency is good with the high data rate, the peak transceiver power typically exceeds 500mW, making the heating problem critical. To the contrary, the UWB based transceiver is shown to achieve <15mW for the data rate of 500Mb/s [7] and can achieve <40mW for Gb/s data transmission.…”

The interest in the ultra-wideband (UWB) technology as a potential wireless standard has been on the decline, but it could be retuned with the need of an ultra-low power low-cost transceiver system for wireless body area network (WBAN) and wireless sensor network (WSN) applications. Promising areas of the UWB applications lie in sub-nJ/bit transceivers, Gb/s proximity communications, low power sensor networks, and mobile healthcare systems. In this paper, a brief overview of the UWB technology and some useful features for next-generation short-range communication systems are discussed.

“…The terms b i and f i are respectively the i th slope value of envelope a(t) and instantaneous frequency f (t) in the piece-wise approximation; c i and ϕ 0,i are the y-intercept of each linear part. Moreover ϕ 0,i insures the continuity during the f (t) integration to obtain the phase ϕ(t) of the signal according to (4). It can be also interesting to consider the envelope with a piece-wise time invariant approach.…”

“…In contrast to low-data-rate transmitters, high-data-rate transmitters have more difficulty in increasing the transmitting power since the average power can easily violate the spectrum mask [1]. To address this challenge, a frequency-hopping technique is used to spread the energy over a wide freq uency range, which allows a higher transmitted power of a single pulse while the average power complies the spectrum mask.…”

“…To address this challenge, a frequency-hopping technique is used to spread the energy over a wide freq uency range, which allows a higher transmitted power of a single pulse while the average power complies the spectrum mask. By employing the FH technique, the transmitting power of the transmitter in [1] is 8 times higher than the conventional one without the FCC mask violation. In this paper, we present a low power 200Mb/s IR-UWB transmitter using the FH technique.…”

A 3-5GHz frequency-hopping (FH) transmitter using an impulse radio ultra-wideband (IR-UWB) signal is designed in a standard 65-nm CMOS technology. A delay-line-based architecture utilizing only static logic gates for pulse generation is employed to achieve low power consumption. The center frequency of the transmitted IR-UW B signal with the fixed bandwidth of 500MHz covers three channels in the low band of UWB spectrum and hops successively from one to another at a rate of 200MHz. Binary phase shift keying (BPSK) modulation schemes are exploited to modulate transmitted signals with further improvement in spectrum characteristics. By employing the FH technique, the energy consumption of the transmitter is 3.6pJ/bit at a data-rate of 200Mb/s with the FCC mask well complied.
