Available in PDF, EPUB and Kindle. Book excerpt: This book argues that only by reforming the international monetary system can we prevent financial crises in the future and the internationalization of the Renminbi, China's national currency, will be an important step in the process.Just as the old saying goes, 'An old building needs to be demolished before a new one can be erected in its place,' there will be no construction without destruction. The commencement of the dismantling of the old monetary system is also the beginning of the construction of the new one. Contrary to Western rhetoric, which portrays China as part of the cause of the recent financial crisis, the author contends that China is actually a victim of the current unjust international economic and monetary system. To address the imbalance and break the dollar-dominated international monetary system, the author calls for the internationalization of the Renminbi and diversification of the international monetary system.Written by one of the foremost financial practitioners in China, this book is thought-provoking and provides a unique Chinese perspective on how the international monetary system should be reformed, what the future system should look like and the role China should play in the process. It is a required reading for anyone interested in understanding China's own vision in its rise in the global political, economic and financial systems.

Download or read book Advanced Frequency Synthesis by Phase Lock written by William F. Egan and published by John Wiley & Sons. This book was released on 2011-10-07 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The latest frequency synthesis techniques, including sigma-delta,Diophantine, and all-digital Sigma-delta is a frequency synthesis technique that has risen inpopularity over the past decade due to its intensely digital natureand its ability to promote miniaturization. A continuation of thepopular Frequency Synthesis by Phase Lock, Second Edition, thistimely resource provides a broad introduction to sigma-delta bypairing practical simulation results with cutting-edge research.Advanced Frequency Synthesis by Phase Lock discusses bothsigma-delta and fractional-n—the still-in-use forerunner tosigma-delta—employing Simulink® models and detailedsimulations of results to promote a deeper understanding. After a brief introduction, the book shows how spurs areproduced at the synthesizer output by the basic process anddifferent methods for overcoming them. It investigates how variousdefects in sigma-delta synthesis contribute to spurs or noise inthe synthesized signal. Synthesizer configurations are analyzed,and it is revealed how to trade off the various noise sources bychoosing loop parameters. Other sigma-delta synthesis architecturesare then reviewed. The Simulink simulation models that provided data for thepreceding discussions are described, providing guidance in makinguse of such models for further exploration. Next, another methodfor achieving wide loop bandwidth simultaneously with fineresolution—the Diophantine Frequency Synthesizer—isintroduced. Operation at extreme bandwidths is also covered,further describing the analysis of synthesizers that push theirbandwidths close to the sampling-frequency limit. Lastly, the bookreviews a newly important technology that is poised to becomewidely used in high-production consumerelectronics—all-digital frequency synthesis. Detailed appendices provide in-depth discussion on variousstages of development, and many related resources are available fordownload, including Simulink models, MATLAB® scripts,spreadsheets, and executable programs. All these features make thisauthoritative reference ideal for electrical engineers who want toachieve an understanding of sigma-delta frequency synthesis and anawareness of the latest developments in the field.

Download or read book CMOS Fractional N Synthesizers written by Bram De Muer and published by Springer Science & Business Media. This book was released on 2005-12-29 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: CMOS Fractional-N Synthesizers starts with a comprehensive introduction to general frequency synthesis. Different architectures and synthesizer building blocks are discussed with their relative importance on synthesizer specifications. The process of synthesizer specification derivation is illustrated with the DCS-1800 standard as a general test case. The book tackles the design of fractional-N synthesizers in CMOS on circuit level as well as system level. The circuit level focuses on high-speed prescaler design up to 12 GHz in CMOS and on fully integrated, low-phase-noise LC-VCO design. High-Q inductor integration and simulation in CMOS is elaborated and flicker noise minimization techniques are presented, ranging from bias point choice to noise filtering techniques. On a higher level, a systematic design strategy has been developed that trades off all noise contributions and fast dynamics for integrated capacitance (area). Moreover, a theoretical DeltaSigma phase noise analysis is presented, extended with a fast non-linear analysis method to accurately predict the influence of PLL non-linearities on the spectral purity of the DeltaSigma fractional-N frequency synthesizers.
