限定空间无线传感器节点电路低功耗的优化

摘要

In the low power consumption of the limited space of wireless sensor node circuit,there has been a drawback of high cost and low accuracy. This paper compares and sums up the principle and characteristics of traditional low-power circuit,and points out the advantages and disadvantages.According to join negative feedback in the particular experimental circuit,the related data which has been acquired is compared,then the conclusions of the lower power consumption is obtained.Meanwhile,with the development of the current situation, the improvements is given.According to analyze the structure of the hardware and software,the simulation results illustration is given,which proves this project has a broad development prospect.%限定空间无线传感器节点的低功耗分析一直存在成本高、精度低的缺点.在对比总结了传统低功耗电路的原理及特点的基础上,指出了其优缺点.通过具体实验电路加入负反馈,得到了相应的数据并进行对比,得出了较低功率消耗的结论.同时,结合目前的发展情况给出了相应的改进措施.通过对硬、软件结构的剖析,给出了仿真结果,证明此方案具有广阔的发展应用前景.
