提案编号：0429766机构：爱荷华州立大学首席研究员：Geiger， RandallTITLE：环境稳定参考器件在SoC兼容工艺中的应用摘要：电压参考器件是许多集成电路中的关键部件。不幸的是，现有最好的电压基准并不具有广泛的商业和军事应用所需的热稳定性，并且在许多新兴电子系统中，现有电压基准的局限性将更加受到关注。这项倡议的重点是采用一种全新的方法来设计电压参考，该方法使用了一种新的环境稳定技术，可以应用于集成电路制造中使用的标准工艺。这项工作的核心是研究使用本地片上加热器测量未校准电压基准的相对热特性的概念，并使用从这些测量中获得的信息来显着提高基准的性能。尽管使用片上加热器的概念在大多数集成电路中是主要关注的问题，因为功耗要求增加，基本上没有关注的是该方法自当地加热器时总功耗非常小,因为总时间的加热器将在整个生活中集成电路通常是远低于1秒。使用当地的芯片上的加热器的概念关键的热稳定性能集成电路应该应用远远超出电压参考,并提供潜力提供了一个更广泛的影响半导体领域。

PROPOSAL NO: 0429766INSTITUTION: Iowa State UniversityPRINCIPAL INVESTIGATOR: Geiger, RandallTITLE: Envirostabilized References for Applications in SoC CompatibleProcessesAbstract:Voltage References are critical components in many integrated circuits. Unfortunately, the best existing voltage references do not have the thermal stability needed for a wide range of commercial and military applications and the limitations of existing voltage references will be of even more concern in a host of emerging electronic systems. This initiative focuses on an entirely new approach to designing voltage references that uses a new environmental stabilization technique that can be applied in standard processes used in the manufacture of integrated circuits. Central to this work is the investigation of the concept of using a local on-chip heater to measure relative thermal characteristics of an uncalibrated voltage reference and of using information obtained from these measurements to significantly improve the performance of the reference. Although the concept of using an on-chip heater would be of major concern in most integrated circuits because of the increased power dissipation requirements, it is of essentially no concern in the proposed approach since the total power dissipation when the local heater is on is very small and because the total time the heater will be on throughout the life of the integrated circuit will typically be much less than 1 sec. The concept of using a local on-chip heater for thermal stabilization of key properties of integrated circuits should have applications well beyond voltage references and offer potential for providing a much broader impact in the semiconductor field.
