Özet:

 

Ultra Wide-Band (UWB) transmissions exhibit performances  vastly superior to existing wireless systems - superlative data-rate  capacity, high security, low cost, low power consumption - and are  emerging as the hottest topic of research for upcoming wireless  generations.  This communication protocol is studied in detail, with  mention of the history and estimates for the near future; the present  and possible applications are mentioned; the advantages and unresolved  issues are detailed; a typical UWB transceiver architecture is  studied; the modulation and coding schemes are enumerated; and the  possibility of long-range communication is touched upon.  Finally, a  new performance-controllable low-noise amplifier (LNA) destined for  UWB systems is described.  Inverse proportionality relations mean that  better values are obtained for the noise figure, power consumption,  bandwidth, and output impedance when the gain is higher.  The  amplifier was simulated in the 0.35{m}m SiGe BiCMOS technology from  ST Microelectronics.  The gain of the LNA is controllable in the range  from 0dB to 29dB; bandwidths of up-to 10GHz are obtained, covering the  entire authorised UWB band; noise figures as low as 2.7dB are  exhibited; the power consumption is always below 7mW; and an excellent  temperature stability is shown - a gain drop of only 0.5dB in the  temperature range from -40 °C to 85 °C.
