项目摘要

Today's low-power electronic systems are designed to handle a high variability in the power demand, for example during transmissions from miniature wireless sensors. However these systems cannot cope with a highly variable power supply. If they are powered by an ambient energy harvester in an environment where the available power is low and sporadic, the system dies once the energy storage becomes depleted or damaged, with start-up being impossible if the power is not increased to a higher steady level. With an increasing number of potential applications of microelectronic systems calling for remote, embedded and miniaturized solutions, sporadic and low power supply and unpredictable energy storage needs to be addressed.This project researches how to design robust and reliable electronics for situations where there is a variable, unreliable source of energy. A number of situations, or states, have been defined, according to the level of depletion of on-board energy storage, and to how variable the power supply is. In the most challenging states, for example where the input power is sporadic and spread over a wide range from nW to mW, modern electronics fails. We call this the "survival zone" and are investigating a combination of techniques from the areas of power electronics and asynchronous microelectronics design to allow devices to operate in this zone. Techniques include control circuits that are able to ride through variable voltages, the detection of states, and reconfigurable hardware resources and control algorithms to suit sporadic and sub-microwatt input power. The chief aim of this project is to produce survival zone design methods for the microelectronics design community.

今天的低功率电子系统被设计成处理电力需求的高度变化性，例如在微型无线传感器的传输期间。然而，这些系统无法应对高度可变的电源。如果它们在可用功率低且不稳定的环境中由环境能量收集器供电，一旦能量存储耗尽或损坏，系统就会死亡，如果功率没有增加到更高的稳定水平，则不可能启动。随着越来越多的微电子系统的潜在应用需要远程、嵌入式和小型化的解决方案，需要解决零星和低功率供应以及不可预测的能量存储问题。本项目研究如何在能源可变、不可靠的情况下设计健壮可靠的电子设备。根据机载储能的耗尽程度和电源的可变程度，已经定义了许多情况或状态。在最具挑战性的国家，例如，输入功率是零星的，分布在从北瓦到兆瓦的广泛范围内，现代电子设备就会失败。我们将其称为“生存区域”，并正在研究电力电子学和异步微电子设计领域的技术组合，以允许设备在该区域运行。技术包括能够通过可变电压的控制电路、状态检测以及可重新配置的硬件资源和控制算法，以适应零星和亚微瓦的输入功率。该项目的主要目的是为微电子设计界提供生存地带设计方法。
