Download or read book A 20 GHz Silicon Germanium HBT Phase Locked Loop PLL for Serial Link Applications microform written by Saniei, Namdar and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2005 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PLL proposed in this thesis is based on an inductorless single-stage ring-type VCO, using a diode bridge doubling method to achieve 20 GHz oscillation frequency in the 47 GHz technology. Self injection locking (SIL), is used for the first time in the design of the VCO. A modified Gilbert cell is used as the phase detector and parasitic components are used as the low pass filter in the PLL. Demand for higher data rate network connections and the expansion of multi-media applications in new generation cellular phones, have increased the need for economical high-speed serial transceivers. An important block in the transceiver is the PLL that plays a major role in both the transmitter and the receiver. This thesis deals with the design and implementation of an inductorless high-speed PLL in a 0.5 mum BiCMOS SiGe-HBT process technology with a unity gain cut off frequency of 47 GHz. The frequency range of the implemented PLL is 12--20 GHz which renders it suitable for 20 and 40 Gb/s systems. The PLL exhibits a phase noise of better than -103 dBc/Hz at 1 MHz offset which translates to near 0.13 ps rms jitter. The total power dissipation of the chip is 221 mW from a single -3.3 V power supply and its area occupied is less than 0.2 mm2. The proposed PLL architecture also has the potential for use in 80 Gb/s serial-links.

Download or read book Logic Synthesis for Asynchronous Controllers and Interfaces written by J. Cortadella and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a long friendship, of a broad international co operation, and of a bold dream. It is the summary of work carried out by the authors, and several other wonderful people, during more than 15 years, across 3 continents, in the course of countless meetings, workshops and discus sions. It shows that neither language nor distance can be an obstacle to close scientific cooperation, when there is unity of goals and true collaboration. When we started, we had very different approaches to handling the mys terious, almost magical world of asynchronous circuits. Some were more theo retical, some were closer to physical reality, some were driven mostly by design needs. In the end, we all shared the same belief that true Electronic Design Automation research must be solidly grounded in formal models, practically minded to avoid excessive complexity, and tested "in the field" in the form of experimental tools. The results are this book, and the CAD tool petrify. The latter can be downloaded and tried by anybody bold (or desperate) enough to tread into the clockless (but not lawless) domain of small-scale asynchronicity. The URL is http://www.lsi. upc. esr j ordic/petrify. We believe that asynchronous circuits are a wonderful object, that aban dons some of the almost militaristic law and order that governs synchronous circuits, to improve in terms of simplicity, energy efficiency and performance.

Download or read book High Spectral Density Optical Communication Technologies written by Masataka Nakazawa and published by Springer Science & Business Media. This book was released on 2010-08-12 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of Internet traf?c in recent years surpassed the prediction of one decade ago. Data stream in individual countries already reached terabit/s level. To cope with the petabit class demands of traf?c in coming years the communication engineers are required to go beyond the incremental improvement of today’s technology. A most promising breakthrough would be the introduction of modulation f- mats enabling higher spectral ef?ciency than that of binary on–off keying scheme, virtually the global standard of ?ber-optic communication systems. In wireless communication systems, techniques of high spectral density modulation have been well developed, but the required techniques in optical frequency domain are much more complicated because of the heavier ?uctuation levels. Therefore the past trials of coherent optical modulation/detection schemes were not successful. However, the addition of high-speed digital signal processing technology is the fundam- tal difference between now and two decades ago, when trials of optical coherent communication systems were investigated very seriously. This approach of digital coherent technology has attracted keen interest among communication specialists, as indicated by the rapid increase in the pioneering presentations at the post-deadline sessions of major international conferences. For example, 32 terabit/s transmission in a ?ber experiment based on this technology was reported in post-deadline session of Optical Fiber Communication Conference (OFC) 2009. The advancement of the digital coherent technologies will inevitably affect the network architecture in terms of the network resource management for the new generation photonic networks, rather than will simply provide with huge transmission capacity.

His current research interests include optical networks, error control coding, constrained coding, coded modulation, turbo equalization, OFDM applications, and quantum error correction. "This wonderful book is the first one to address the rapidly emerging optical OFDM field. Written by two leading researchers in the field, the book is structured to comprehensively cover any optical OFDM aspect one could possibly think of, from the most fundamental to the most specialized. The book adopts a coherent line of presentation, while striking a thoughtful balance between the various topics, gradually developing the optical-physics and communication-theoretic concepts required for deep comprehension of the topic, eventually treating the multiple optical OFDM methods, variations and applications. In my view this book will remain relevant for many years to come, and will be increasingly accessed by graduate students, accomplished researchers as well as telecommunication engineers and managers keen to attain a perspective on the emerging role of OFDM in the evolution of photonic networks." -- Prof. Moshe Nazarathy, EE Dept., Technion, Israel Institute of Technology The first book on optical OFDM by the leading pioneers in the field The only book to cover error correction codes for optical OFDM Applications of OFDM to free-space communications, optical access networks, and metro and log haul transports show optical OFDM can be implemented An introduction to signal processing for optical communications An introduction to optical communication fundamentals for the wireless engineer
Download or read book Mathematical Theory of Diffraction written by Arnold Sommerfeld and published by Springer Science & Business Media. This book was released on 2004 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: A. Sommerfeld's "Mathematische Theorie der Diffraction" marks a milestone in optical theory, full of insights that are still relevant today. In a stunning tour de force, Sommerfeld derives the first mathematically rigorous solution of an optical diffraction problem. Indeed, his diffraction analysis is a surprisingly rich and complex mix of pure and applied mathematics, and his often-cited diffraction solution is presented only as an application of a much more general set of mathematical results. This complete translation, reflecting substantial scholarship, is the first publication in English of Sommerfeld's original work. The extensive notes by the translators are rich in historical background and provide many technical details for the reader.
