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.

提案编号：0429766INSTUTION：爱荷华州立大学PRINCIPAL研究员：Geiger，RandallTITLE：SoC兼容工艺中应用的环境稳定参考摘要：电压基准是许多集成电路中的关键部件。遗憾的是，现有最好的基准电压源不具备广泛的商业和军事应用所需的热稳定性，现有基准电压源的局限性在许多新兴电子系统中将更加令人担忧。这一倡议侧重于一种全新的电压基准设计方法，该方法使用一种新的环境稳定技术，该技术可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来测量未校准基准电压的相对热特性的概念，以及使用从这些测量中获得的信息来显著提高基准电压的性能。虽然由于增加的功率消耗要求，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，但是在所提出的方法中基本上不需要考虑，因为当本地加热器开启时总的功率损耗非常小，并且因为加热器在集成电路的整个生命周期中开启的总时间通常将远远小于1秒。使用本地片上加热器来热稳定集成电路的关键特性的概念应该远远超出电压基准的应用范围，并有可能在半导体领域提供更广泛的影响。
