UWB Receiver

This is a PhD dissertation submitted by S.Y. Lee. The copyright is reserved by the author and Uni. of South CA... The report is on Ultra-wideband (UWB) receiver front-end design. In the report, the author gave detailed analysis on RF receiver front-end circuit design techniques and RF system design. In addition, UWB technology was presented in the report. In this phD study, the author designed a one-stage shunt-feedback single-ended LNA and a novel Mixer. The bandwidth of the front-end was only 0.8 GHz. All the circuits were designed in SiGe 0.5um process. (It was done in 2002. So the technology was a bit too old)
P.S. My undergraduate final year Project (FYP) was  on UWB transmitter design. I have studied this dissertation completely. It is very very useful. That's why I want to share it with every RF transceiver designer.

Abstract:

The wireless system is being rapidly proliferated in our life. The growing of capacity in wireless communication requires a new type of wireless communication method which does not e®ect current systems. A new system that ful¯lls this requirement is the Ultra-Wide bandwidth (UWB) impulse radio. In addition, the UWB system also promises low power, covert communication, and very high processing gain. In this dissertation, an UWB system which can lead this next generation of communications of an UWB radio is introduced.

In this work, the complete front-end of an UWB radio and its components are described in a detailed analysis. The main focus of this work is the design of the UWB system's wide-bandwidth components. In the course of this dissertation, the UWB system, its UWB signal properties and its possible system architecture are described. Based on these system characteristics, required RF components are designed with IBM's Silicon Germanium (SiGe) 0.5 ¹m process and analyzed. Using this technology, the two important front-end functions highlighted in this work are signal ampli¯cation for wide-bandwidth and correlation detection of the signal.

Theoretical investigation of the conventional front-end components illustrates de¯ciencies of current technologies that frustrate the wide-bandwidth design task. Along with these investigations, possible solutions for wide-bandwidth components design are provided. s ¯nal goals of this dissertation, the new UWB system design has been constructed with a sinusoidal correlator template, and a wide-bandwidth LNA and mixer have been designed. The LNA achieves 0.8 GHz bandwidth, 8.4 dB °at gain over its frequency range, 3 dB noise ¯gure and -6 dBm dynamic range with shunt-series

feedback topology. The mixe achieves 13 dB conversion gain, 15 dB noise ¯gure and -6.3 dB dynamic range using the CS-CG pair as the mixer's transconductance.

国外的好的博士论文大部分内容应该都是比较通俗易懂的。瞅瞅先。
