Current Sense Amplifiers for Embedded SRAM in High-Performance System-on-a-Chip Designs

By: Bernhard Wicht

System-on-a-chip (SoC) designs result in a wide range of high-complexity, high-value semiconductor products. As the technology scales towards smaller feature sizes and chips grow larger, a speed limitation arises due to an in creased RC delay associated with interconnection wires. Innovative circuit techniques are required to achieve the speed needed for high-performance signal processing. Current sensing is considered as a promising circuit class since it is inherently faster than conventional voltage sense amplifiers. How ever, especially in SRAM, current sensing has rarely been used so far. Practi cal implementations are challenging because they require sophisticated analog circuit techniques in a digital environment. The objective of this book is to provide a systematic and comprehen sive insight into current sensing techniques. Both theoretical and practical aspects are covered. Design guidelines are derived by systematic analysis of different circuit principles. Innovative concepts like compensation of the bit line multiplexer and auto-power-down will be explained based on theory and experimental results. The material will be interesting for design engineers in industry as well as researchers who want to learn about and apply current sensing techniques. The focus is on embedded SRAM but the material presented can be adapted to single-chip SRAM and to any other current-providing memory type as well. This includes emerging memory technologies like magnetic RAM (MRAM) and Ovonic Unified Memory (OUM). Moreover, it is also applicable to array like structures such as CMOS camera chips and to circuits for signal trans mission along highly capacitive busses.

Highly Integrated Gate Drivers for Si and GaN Power Transistors

By: Achim Seidel,Bernhard Wicht

This book explores integrated gate drivers with emphasis on new gallium nitride (GaN) power transistors, which offer fast switching along with minimum switching losses. It serves as a comprehensive, all-in-one source for gate driver IC design, written in handbook style with systematic guidelines. The authors cover the full range from fundamentals to implementation details including topics like power stages, various kinds of gate drivers (resonant, non-resonant, current-source, voltage-source), gate drive schemes, driver supply, gate loop, gate driver power efficiency and comparison silicon versus GaN transistors. Solutions are presented on the system and circuit level for highly integrated gate drivers. Coverage includes miniaturization by higher integration of subfunctions onto the IC (buffer capacitors), as well as more efficient switching by a multi-level approach, which also improves robustness in case of extremely fast switching transitions. The discussion also includes a concept for robust operation in the highly relevant case that the gate driver is placed in distance to the power transistor. All results are widely applicable to achieve highly compact, energy efficient, and cost-effective power electronics solutions.

Refurbishment Manual

Maintenance, Conversions, Extensions

By: Georg Giebeler,Harald Krause,Rainer Fisch,Florian Musso,Bernhard Lenz,Alexander Rudolphi

Planning tasks involving existing structures are currently among the most common types of contract, and almost every structure makes different demands and raises individual problems. Reflecting this state of affairs, there are a dizzying number of publications on the market, most of which are quite specialized. The Refurbishment Manual cuts through this jungle of publications. It defines terms and concepts, combines the narrowly focused perspectives of the specialists, and offers concrete approaches to this wide-ranging topic. The Refurbishment Manual closes the gap between basic constructional literature and one-sided, highly specialized technical literature. It constitutes a practical planning aid on the subject of refurbishment, providing a basic introduction to the relevant aspects of building physics, fire protection, sustainability and energy, hazardous materials, construction materials for interior and façade, historic preservation, and technical building equipment. It offers concrete tips on planning steps, methods of building analysis, and cost benchmarks, as well as clear constructional solutions with built projects as examples. A unique feature of the volume is the specially developed timeline, which allows the planner to quickly grasp, categorize, and evaluate a concrete building task and thus obtain an efficient planning overview. Planungsaufgaben im Bestand gehören derzeit zu den häufigsten Auftragsarten und nahezu jedes Bauwerk stellt andere Anforderungen und weist individuelle Probleme auf. Analog dazu gibt es auf dem Markt eine fast unüberschaubare Anzahl Publikationen in meist sehr spezialisierter Form. Der Sanierungsatlas möchte Licht in diesen Publikationsdschungel bringen: Er definiert Begrifflichkeiten, vereint die fokussierenden Betrachtungsweisen der Fachleute und vermittelt konkrete Herangehensweisen an diese weit gefächerte Thematik. Der Sanierungsatlas schließt die Lücke zwischen grundlegender Baukonstruktions- und sehr einseitig spezialisierter Fachliteratur. Das Buch stellt eine praktische Planungshilfe zum Thema Sanierung dar – und zwar in Form von relevanter Grundlagenvermittlung zu Bauphysik, Brandschutz, Nachhaltigkeits- und energetischen Aspekten, Schadstoffen, Baustoffen im Innenraum und an der Fassade, zu Aspekten der Denkmalpflege ebenso wie zur technischen Gebäudeausstattung. Er liefert konkrete Hinweise zu Planungsschritten, Methoden der Bauanalyse und Kostenkennwerten sowie anschauliche Konstruktionslösungen am Beispiel gebauter Projekte. Einzigartig ist die speziell entwickelte Zeitschiene, mit deren Hilfe eine konkrete Bauaufgabe schnell erfasst, kategorisiert und bewertet werden kann – und die dem Planer somit einen effizienten Planungsüberblick verschafft.

Glass in Building

Principles, Applications, Examples

By: Bernhard Weller,Stefan Unnewehr,Silke Tasche,Kristina Härth

Glass in Building" opens up a whole range of fascinating design possibilities for the planning architect. Glass has long served as a translucent room closing element, but its range of possible uses is actually much wider. It not only offers protection against the external world, for example, noise or fire; despite its apparent fragility, it can even take on load-bearing functions in supporting structures. In combination with various different finishing methods, materials, and coatings, it also satisfies exacting structural-physical standards. "Glass in Building" offers a clear, compact, and illustrated overview of the material-appropriate use of this varied and versatile material in building construction and provides information that goes far beyond the basics on designing with glass and producing and using specialized glass products, as well as on the building and planning regulations that must be taken into account when constructing with glass. A selection of exemplary realized projects rounds out the theoretical section. Das Bauen mit Glas eröffnet dem planenden Architekten faszinierende gestalterische Möglichkeiten. Schon lange dient es als lichtdurchlässiger Raumabschluss, ist aber weitaus vielfältiger einsetzbar: Glas bietet nicht nur Schutz vor der Aussenwelt, etwa gegen Lärm oder Feuer, sondern kann trotz seiner vermeintlichen Zerbrechlichkeit sogar lastabtragende Funktionen innerhalb eines Tragwerks übernehmen. In Kombination mit verschiedenen Veredelungsmethoden, Materialien und Beschichtungen erfüllt es auch hohe bauphysikalische Anforderungen. „Detail Practice: Konstruktiver Glasbau" liefert einen kompakten, anschaulichen Überblick über den materialgerechten Einsatz dieses facettenreichen Baustoffs in der Baukonstruktion und vermittelt weit über die Grundlagen hinausreichende Informationen zum Entwerfen mit Glas, zur Herstellung und Anwendung spezieller Glasprodukte sowie zu den baurechtlichen Regelungen, die im Glasbau zu berücksichtigen sind. Eine Auswahl beispielhafter realisierter Projekte rundet den theoretischen Teil ab.
