无线传感器网络系统现在被国际社会应用于商业、医疗保健和安全方面的关键应用。这些系统具有独特的特点，并面临许多实施挑战。其中，在有限的能量供应下，无线传感器节点的长工作寿命的要求施加了最严格的设计约束。这就需要创新的设计方法来满足这一严格的要求。本文首先概述了传感器网络的无线技术。然后描述通信系统、电路设计和系统封装考虑。无线电架构和电路技术的选择进行了讨论，重点是低功耗实现和工作特性，以满足传感器网络应用的要求。最后，最具挑战性的组成部分，一个完整的低功耗CMOS接收器系统的设计，实施和性能，展示这些设计原则。
Wireless sensor network systems are now being applied by an international community for critical applications in commerce, healthcare, and security. These systems have unique characteristics and face many implementation challenges. Among all, the requirement of long operating life for a wireless sensor node under limited energy supply imposes the most severe design constraints. This calls for innovative design methodologies to address this rigorous requirement. This article first provides an overview of wireless technologies for sensor networks. It then describes communication system, circuit design, and system packaging considerations. The selection of radio architectures and circuit techniques is discussed with an emphasis on the low-power implementation and operating characteristics that match requirements of sensor network application. Finally, the design, implementation, and performance of the most challenging component, a complete low-power CMOS receiver system, is presented to demonstrate these design principles.
