Thermal And Power Management Of Integrated Circuits

In Thermal and Power Management of Integrated Circuits, power and thermal management issues in integrated circuits during normal operating conditions and stress operating conditions are addressed. Thermal management in VLSI circuits is becoming an integral part of the design, test, and manufacturing. Proper thermal management is the key to achieve high performance, quality and reliability. Performance and reliability of integrated circuits are strong functions of the junction temperature. A small increase in junction temperature may result in significant reduction in the device lifetime. This book reviews the significance of the junction temperature as a reliability measure under nominal and burn-in conditions. The latest research in the area of electro-thermal modeling of integrated circuits will also be presented. Recent models and associated CAD tools are covered and various techniques at the circuit and system levels are reviewed. Subsequently, the authors provide an insight into the concept of thermal runaway and how it may best be avoided. A section on low temperature operation of integrated circuits concludes the book.

"As integrated circuits get smaller and more complex, power densities are increasing, leading to more heat generation. Dealing with this heat is fast becoming the most important design bottleneck of current and future integrated circuits, where power envelopes are defined by the ability of the system to dissipate the generated heat. Thermal effects are forcing chip designers to apply conservative design margins, creating sub-optimal results. At a larger scale, cooling is the second most costly item in the electricity bills of well-designed high-performance computing and data centers, costing 30-50% of the total. Thermal monitoring and management in integrated circuits is therefore becoming increasingly important. This book covers thermal monitoring and management in integrated circuits, with a focus on devices and materials that are intimately integrated on-chip as opposed to in-package or on-board. The devices and circuits discussed include various designs used for the purpose of converting temperature to a digital measurement and actively biased circuits that reverse thermal gradients on chips for the purpose of cooling. Topics covered include an overview of heat in integrated circuits and systems, on-chip temperature sensing, dynamic thermal management, active cooling, and mitigating thermal events at the system-level and above"--Provided by publisher.

This book will introduce various power management integrated circuits (IC) design techniques to build future energy-efficient “green” electronics. The goal is to achieve high efficiency, which is essential to meet consumers’ growing need for longer battery lives. The focus is to study topologies amiable for full on-chip implementation (few external components) in the mainstream CMOS technology, which will reduce the physical size and the manufacturing cost of the devices.
