Managing Temperature Effects in Nanoscale Adaptive Systems

This book presents a variety of new techniques for detecting, controlling and exploiting the impact of temperature variations on nanoscale circuits and systems. Covers thermal-aware system design, management of temperature-induced faults, new sensors and more.

This book discusses new techniques for detecting, controlling, and exploiting the impacts of temperature variations on nanoscale circuits and systems. A new sensor system is described that can determine the temperature dependence as well as the operating temperature to improve system reliability. A new method is presented to control a circuit's temperature dependence by individually tuning pull-up and pull-down networks to their temperature-insensitive operating points. This method extends the range of supply voltages that can be made temperature-insensitive, achieving insensitivity at nominal voltage for the first time.

Provides background on aspects of nanoscale circuits and systems that are affected by temperature, how they are affected by temperature, and what systems can be used to reduce these effects Describes chip implementation details of a new type of temperature sensor that can ensure reliable operation across multiple temperature dependences Includes new methods for achieving temperature insensitivity with example circuits and fabrication-related details such as process variation management Includes supplementary material: sn.pub/extras
