The Design Of Low-voltage, Low-power Sigma-delta Modulators

RRP $546.99

Oversampling techniques based on sigma-delta modulation are widely used to implement the analog/digital interfaces in CMOS VLSI technologies. This approach is relatively insensitive to imperfections in the manufacturing process and offers numerous advantages for the realization of high-resolution analog-to-digital (A/D) converters in the low-voltage environment that is increasingly demanded by advanced VLSI technologies and by portable electronic systems. In The Design of Low-Voltage, Low-Power Sigma-Delta Modulators, an analysis of power dissipation in sigma-delta modulators is presented, and a low-voltage implementation of a digital-audio performance A/D converter based on the results of this analysis is described.
Although significant power savings can typically be achieved in digital circuits by reducing the power supply voltage, the power dissipation in analog circuits actually tends to increase with decreasing supply voltages. Oversampling architectures are a potentially power-efficient means of implementing high-resolution A/D converters because they reduce the number and complexity of the analog circuits in comparison with Nyquist-rate converters. In fact, it is shown that the power dissipation of a sigma-delta modulator can approach that of a single integrator with the resolution and bandwidth required for a given application. In this research the influence of various parameters on the power dissipation of the modulator has been evaluated and strategies for the design of a power-efficient implementation have been identified.
The Design of Low-Voltage, Low-Power Sigma-Delta Modulators begins with an overview of A/D conversion, emphasizing sigma-delta modulators. It includes a detailed analysis of noise in sigma-delta modulators, analyzes power dissipation in integrator circuits, and addresses practical issues in the circuit design and testing of a high-resolution modulator.
The Design of Low-Voltage, Low-Power Sigma-Delta Modulators will be of interest to practicing engineers and researchers in the areas of mixed-signal and analog integrated circuit design.

Eye Voltage

The Dude says, “It’s far out, Man.” Do we need to say more? These 50 optical illusions will provide hours of totally spaced out wonderment. It presents content that is confounding and stimulating to the sober viewer but adds extra irreverence by playing off--and playfully joking on—the possibility of the reader being in an altered state. Text consists largely of very short introductions to chapters and captions (where necessary). Will include classic optical illusions that have been “stonerfied” by being printed in vibrant colors, Escher-type visual riddles, psychedelic typographics (in the mannor of the1960’s film noir artist), magic eye images that allow 3D shapes to emerge from white noise backgrounds (the shapes are bongs, hemp leaves, and other stoner tools). Every aspect of the book will be treated as part of the optical illusions, such as, printing all page numbers in reverse, having hemp seeds with drop shadows in the gutter of the book to simulate the effect as if the book had been used to separate bud seeds from ganja leaves, as was done in the days of record albums years ago. Would make a great collection addition for any brain gamer, puzzle master, or champion stoner.

The story of Sexy Sadie as told by herself from prison. A shocking and horrific account as to what happened and why, explaining the real philosophy behind her mass murdering - a powerful belief system that shakes one's own sense of stability and understanding about the world and people around us. Are you ready to open your mind? This book is for adults. Contains graphic descriptions of family dysfunction, swearing, sex, drug use, murder, and justification for murder. 'Me, well I wanted to explore the spiritual boundaries of the human being. You know, how people feel and react to evil. You know about karma - what goes around comes around don't you?' 'Hmm, yeah...' 'Huh, that's just part of it though. You know that every early death, every evil committed against a person results in equal goodness elsewhere?' 'What? What?' 'Yeah. Pain is goodness. It is natural then that pleasure is badness, evil. So there is a circle: the more pain the more pleasure, the more pleasure, the more pain.' 'Yeah, but you guys, you lived a life of pleasure, drugs and sex.' 'Yeah.' 'So, what pain was there in doing that? You were hardly balancing out the karma were you?' 'The pleasure we got from life, of living by our own rules - we had none - meant we had the power, inside each one of us, to continue the cycle of pain, spread it into society and help charge-up the karma cycle. The pain we caused meant more happiness.' 'Happiness is a warm gun?' 'Ha-ha, you have it!' 'It is utterly mad.' 'You see the power of what I'm saying. It scares you.' 'Of course it does. How can you warp logic so much that innocent people die? For such a dire and terrifying possibility, that death, that pain, are good things. That they cause happiness.' 'Yet you instinctively knew that a warm gun equals happiness?' 'It's the name of a fucking song, not some metaphysical empiricism!' 'Yet you connected the idea and the song instantly.' 'It is not that difficult. You know, to make "happiness" you cause pain.' 'Right..."

Inspired by a new revival of worldwide interest in extra-high-voltage (EHV) and ultra-high-voltage (UHV) transmission,High Voltage Engineering merges the latest research with the extensive experience of the best in the field to deliver a comprehensive treatment of electrical insulation systems for the next generation of utility engineers and electric power professionals. The book offers extensive coverage of the physical basis of high-voltage engineering, from insulation stress and strength to lightning attachment and protection and beyond.

Presenting information critical to the design, selection, testing, maintenance, and operation of a myriad of high-voltage power equipment, this must-have text:

  • Discusses power system overvoltages, electric field calculation, and statistical analysis of ionization and breakdown phenomena essential for proper planning and interpretation of high-voltage tests
  • Considers the breakdown of gases (SF6), liquids (insulating oil), solids, and composite materials, as well as the breakdown characteristics of long air gaps
  • Describes insulation systems currently used in high-voltage engineering, including air insulation and insulators in overhead power transmission lines, gas-insulated substation (GIS) and cables, oil-paper insulation in power transformers, paper-oil insulation in high-voltage cables, and polymer insulation in cables
  • Examines contemporary practices in insulation coordination in association with the International Electrotechnical Commission (IEC) definition and the latest standards
  • Explores high-voltage testing and measuring techniques, from generation of test voltages to digital measuring methods

With an emphasis on handling practical situations encountered in the operation of high-voltage power equipment,High Voltage Engineering provides readers with a detailed, real-world understanding of electrical insulation systems, including the various factors affecting-and the actual means of evaluating-insulation performance and their application in the establishment of technical specifications.
