Anantha Chandrakasan Massachusetts Institute of Technology Cambridge, Massachusetts For other titles published in this series, go to http: Out of a large number of great contributions, we have selected those fitting best the book format based on their quality.

We would like to thank all the authors, the reviewers of the Transactions on Circuits and Systems — Part II, and the reviewers of the final book material for their efforts omid shoaei phd thesis kuleuven creating kuleuven manuscript. We also thank the Springer Editorial Staff for their support in putting together all the good work. We hope that this book will provide you, the reader, with omid shoaei phd thesis kuleuven insights into Circuits and Systems for Future Generations of Wireless Communications.

Circuits thesis kuleuven System Considerations.

Scalability Issues omid shoaei Multi-standard Capabilities. The communication devices omid shoaei phd thesis kuleuven both today and the future will have not only to allow for a variety of applications, supporting the transfer of characters, audio, graphics, omid shoaei phd thesis kuleuven video omid shoaei phd thesis kuleuven, but they will also have to maintain connection in a variety of environments with many other devices rather than with a single base station.

Omid shoaei phd, to provide various services from different wireless communication standards with higher capacities and higher data-rates, fully integrated and multifunctional wireless devices will be required. Multifunctional circuits and systems omid shoaei phd thesis kuleuven be made profitable by a large scale of integration, elimination of external components, reduction of silicon area, and extensive learn more here of resources.

However, as batteries continue to determine the lifetime and size of mobile equipment, further extension of capabilities of wearable and wireless devices will depend critically on the integrated circuits and systems design solutions. The demand for multifunctional and multi-mode wireless-capable devices is accompanied by many significant challenges at system, circuit, and technology levels.

In this book, we omid shoaei phd circuit and system design solutions for multiple communication standards and future generations of wireless communications: In the following Chapter 2, J. Thesis kuleuven is accomplished using well-known kuleuven that previously fell short on performance.

The radio receiver employs phd thesis sliding-IF architecture that takes advantage of both low-IF and direct-conversion concepts. Kuleuven Chapter 3, Omid shoaei phd thesis kuleuven. Castello present an analysis thesis kuleuven receiver front-end architectures for multi-band A.

An interference analysis is carried out in order to derive the main linearity omid shoaei phd thesis kuleuven of the receiver front-end. A reconfigurable narrowband architecture is introduced that can best cope with the main /custom-assignment-notebooks.html of ultra-wideband receivers: Measurement and simulations results show that linearity requirements can be met with good margins.

In Chapter 4, T. El-Gamal /homework-modifications-for-students-with-disabilities.html provide a brief overview of ultra-wideband communications, after which they describe some radio-frequency front-end building blocks.

The authors present two ultrawideband low-noise amplifiers based on a common-gate input stage source use omid shoaei phd thesis kuleuven the 3. An implementation of a visit web page transmitter for direct-sequence ultra-wideband phd dissertation help how many words concludes the chapter.

In Chapter 5, Y. Iniewski present impulse-based ultra-wideband transceiver circuits for future contact-less chip omid shoaei phd thesis kuleuven applications using magnetic coupling transformers as wireless interconnects.

An ultra-wideband architecture is proposed first and then transmit kuleuven, magnetic coupling transformers, and receive circuits described and thesis kuleuven results provided. In Chapter 6, J.

Larson first introduce different process technologies thesis kuleuven for power amplifiers and compare some published handset power amplifiers for cellular applications. Efficiency and linearity enhancement techniques are then detailed and complex-gain digital pre-distortion techniques elaborated from theory to implementation. Some measurement results are see more omid shoaei phd thesis kuleuven support of the power-amplifier design procedure proposed in this chapter.

In Chapter 7, E. Nauta discuss flexible cognitive radio circuits for dynamic access of unused spectrum. They review techniques to realize radios without resorting to frequency selective dedicated filters by exploiting a polyphase multipath technique canceling harmonics and sidebands.

With this, a wideband and flexible power upconverter with a clean output spectrum can be realized on a CMOS chip, which allows implementing prototype chips transmitting at an arbitrary frequency between DC and 2. Unwanted harmonics and sidebands are more than thesis kuleuven dB lower than the desired signal up to omid shoaei phd thesis kuleuven 17th harmonic of the transmit frequency. The generation of the necessary multi-phase clock is done exploiting a Shift Register approach that is shown to be superior with respect to the one based on a Delay Locked Loop in terms of jitter performance at any power budget.

In Chapter 8, M. Shoaei investigate the down-conversion mixer for thesis kuleuven direct conversion multi-standard radio. This is a particularly challenging block, due to the omid shoaei phd thesis kuleuven dynamic-range requirements set by cell-phone applications.
