The past 35 years have seen a very rapid advancement in technology on many fronts. This was constantly driven by increasing needs and expanding markets for higher performance and higher-speed products, applications, and services that we have come to depend upon for convenience and enjoyment. Integrated circuits (ICs), very large scale integration (VLSI) technologies, and microelectronics have played a key role in this process by providing very sophisticated, and often complex, signal processing capabilities at reasonable cost. These technologies will continue to be at the core of the growth of future and emerging systems for a wide range of applications, such as information and communications technologies (ICT), health care and pharmaceutical, aerospace, automotive, and energy and environment. New and emerging technologies such as very advanced wireless communication systems, micro electromechanical systems (MEMS), and nanoelectronics will augment existing technologies in order to enable the envisioned microsystems of the future. The objective of this proposal is to advance the state-of-the-art of the radio frequency integrated circuits (RFICs) technology, which is at the heart of the wireless revolution we are all experiencing, and is expected to be for years to come. To achieve this, we will capitalize on new and emerging technologies, such as RF-MEMS and ultra-wideband (UWB) communications schemes. The latter transmit information as very weak signals over a wide frequency spectrum. This is known to have low probability of detection by unintended radio systems, and to have excellent multipath immunity and less susceptibility to interferences, thus improving the quality of service. Also, it has potential for very low-power consumption and wider bandwidth, thus can enable longer battery lives and faster wireless communications.

在过去的35年里，技术在许多方面都取得了非常迅速的进步。这是不断增长的需求和不断扩大的市场对更高性能和更高速度的产品、应用和服务的推动，我们已经开始依赖于方便和享受。集成电路（ic）、超大规模集成电路（VLSI）技术和微电子技术在这一过程中发挥了关键作用，它们以合理的成本提供了非常复杂的信号处理能力。这些技术将继续成为未来和新兴系统增长的核心，用于广泛的应用，如信息和通信技术（ICT）、医疗保健和制药、航空航天、汽车、能源和环境。新兴技术，如非常先进的无线通信系统、微机电系统（MEMS）和纳米电子学，将增强现有技术，以实现未来设想的微系统。该提案的目标是推动射频集成电路（rfic）技术的发展，该技术是我们正在经历的无线革命的核心，预计将在未来几年内实现。为了实现这一目标，我们将利用新兴技术，如RF-MEMS和超宽带（UWB）通信方案。后者以非常微弱的信号在宽频谱上传输信息。众所周知，这种方式被意外无线电系统发现的概率很低，而且具有出色的多径免疫能力，对干扰的敏感性较低，从而提高了服务质量。此外，它还具有极低功耗和更宽带宽的潜力，因此可以实现更长的电池寿命和更快的无线通信。
