Book Description
Thanks to the advance of semiconductor and communication technology, the wireless communication market has been booming in the last two decades. It evolved from simple pagers to emerging third-generation (3G) cellular phones. In the meanwhile, broadband communication market has also gained a rapid growth. As the market always demands hi- performance and low-cost products, circuit designers are seeking hi- integration communication devices in cheap CMOS technology. The phase-locked loop frequency synthesizer is a critical component in communication devices. It works as a local oscillator for frequency translation and channel selection in wireless transceivers and broadband cable tuners. It also plays an important role as the clock synthesizer for data converters in the analog-and-digital signal interface. This book covers the design and analysis of PLL synthesizers. It includes both fundamentals and a review of the state-of-the-art techniques. The transient analysis of the third-order charge-pump PLL reveals its locking behavior accurately. The behavioral-level simulation of PLL further clarifies its stability limit. Design examples are given to clearly illustrate the design procedure of PLL synthesizers. A complete derivation of reference spurs in the charge-pump PLL is also presented in this book. The in-depth investigation of the digital CA modulator for fractional-N synthesizers provides insightful design guidelines for this important block.

High-speed CMOS Dual-modulus Prescalers for Frequency Synthesis

Pages : 126
Book Description
Phase-locked loop (PLL) frequency synthesizers lie at the heart of most radio transceivers. An important objective of the electronics and communications industry is to design high-speed building blocks which dissipate the lowest possible power, and to accomplish this with the cheapest technology. The dual-modulus prescaler is one of the key components of a PLL-based frequency synthesizer, operating at gigahertz frequencies. While several previous implementations have utilized the advantages of a high-speed, but expensive technology, the growing trend towards integrating the frequency synthesizer on a single chip is the motivation behind silicon-CMOS implementations. This thesis addresses the issues in the design of CMOS prescalers for frequency synthesis. A design methodology is obtained to improve the performance of integrated prescalers using the current mode style of operation. An 8/9 dual-modulus prescaler prototype has been designed to obtain speeds of the order of 2.5-3 GHz while minimizing the power consumed to 2.5 mW. The circuit was implemented in a 0.25[mu]m National BiCMOS process. Measurement results of the prototype have also been obtained.
Design of Fractional-N Phase Locked Loops for Frequency Synthesis from 30 to 40 GHz

Book Description
"High-frequency fractional-N PLLs in CMOS technology in the 30 to 40 GHz are very dicult to design when considering power, area, phase noise requirements and frequency range of operation. One of the diculties is to synthesize the loop lter of the PLL such that it meets the phase noise characteristics using the information available for all the components that make up the PLL. At the same time, predicting the phase noise output of the PLL using extracted layout results takes a long time to simulate and often the solution does not converge, thereby lengthening the design cycle. This thesis proposes a new methodology for designing high performance wide-band fractional-N PLLs in the 30-40 GHz range. The method begins by rst designing the phase-frequency detector/charge-pump, voltage-controlled oscillator and frequency divider circuit for realization in a specic CMOS technology. The method of choice mixes insight deemed from both a theoretical and simulation perspective. Next, the loop lter is derived based on the layout extracted behaviour of each component. Once complete, all components of the PLL are described using the high-level description language of Verilog-A available in the Cadence tool set over its full range of operating characteristics. Ideally, these components would be fabricated rst and characterized afterward. The Verilog-A description of the PLL enables a fast and ecient simulation of the complete PLL in a closed-loop conguration. This latter steps allows further optimization of the overall design. Two chips have been fabricated; one in a 0.13 m CMOS process from IBM and another in a 65 nm CMOS process from TSMC. One chip contain the design of a 28 GHz VCO and another containing the design of a programmable frequency divider circuit. Experimental results for both chip are provided." --

ISBN: 364220158X
Category : Science
Languages : en
Pages : 340
Book Description
This book demonstrates how the new phenomena in superconductivity on the nanometer scale (FFLO state, triplet superconductivity, Crossed Andreev Reflection, synchronized generation etc.) serve as the basis for the invention and development of novel nanoelectronic devices and systems. It demonstrates how rather complex ideas and theoretical models, like odd-pairing, non-uniform superconducting state, pi-shift etc., adequately describe the processes in real superconducting nanostructues and novel devices based on them. The book is useful for a broad audience of readers, researchers, engineers, PhD-students, lectures and others who would like to gain knowledge in the frontiers of superconductivity at the nanoscale.

Book Description
This book is dedicated to Prof. Dr. Heinz Gerhäuser on the occasion of his retirement both from the position of Executive Director of the Fraunhofer Institute for Integrated Circuits IIS and from the Endowed Chair of Information Technologies with a Focus on Communication Electronics (LIKE) at the Friedrich-Alexander-Universität Erlangen-Nürnberg. Heinz Gerhäuser's vision and entrepreneurial spirit have made the Fraunhofer IIS one of the most successful and renowned German research institutions. He has been Director of the Fraunhofer IIS since 1993, and under his leadership it has grown to become the largest of Germany's 60 Fraunhofer Institutes, a position it retains to this day, currently employing over 730 staff. Likely his most important scientific as well as application-related contribution was his pivotal role in the development of the mp3 format, which would later become a worldwide success. The contributions to this Festschrift were written by both Fraunhofer IIS staff and external project team members in appreciation of Prof. Dr. Gerhäuser's lifetime academic achievements and his inspiring leadership at the Fraunhofer IIS. The papers reflect the broad spectrum of the institute's research activities and are grouped into sections on circuits, information systems, visual computing, and audio and multimedia. They provide academic and industrial researchers in fields like signal processing, sensor networks, microelectronics, and integrated circuits with an up-to-date overview of research results that have a huge potential for cutting-edge industrial applications.
