【摘要】：无线传感网结合了传感器技术、无线网络技术和数据处理技术,通过网络末端的传感器感知外部信息,并将信息上传,实现信息共享,无线传感网已被广泛应用在军事、农业、工业以及个人生活中。无线传感器节点是无线传感网络的核心器件之一。随着科技的发展,无线传感器节点向着低功耗化、小型化、集成化发展,因此传感器芯片的设计是整个传感器节点发展的需要。本文主要设计的是应用于变电站中的无线测温节点芯片。在芯片设计之前,本文首先对低功耗无线传感器做了大量的调研,确定了占空比的工作方式。针对系统的设计需求,对整个测温节点的架构和芯片的设计参数做了详细的讨论,并完成了芯片的整体架构设计。之后,本文分别详细介绍了芯片的数字电路模块和模拟电路模块的设计,包括数字控制器、带隙压差电路、温度传感器、模数转换器等。电路的设计经过了相应的数字电路设计工具和模拟电路设计工具的仿真检验,并完成了版图设计。本芯片是在XFAB 0.35μm工艺下进行设计的。芯片唤醒模式下功耗为36.5mW,然而利用占空比的方法可使得测温芯片的平均功耗低至0.6μW左右。芯片可使用自取能或者电池供电,测温范围为-20~120℃,分辨率0.16℃。
[Abstract]:Wireless sensor network combines sensor technology, wireless network technology and data processing technology, through the sensor at the end of the network to perceive external information, and upload the information to achieve information sharing. Wireless sensor network has been widely used in military, agriculture, industry and personal life. Wireless sensor node is one of the core devices of wireless sensor network. With the development of technology. Wireless sensor nodes develop towards low power consumption, miniaturization and integration. Therefore, the design of sensor chip is the need of the whole sensor node development. In this paper, we do a lot of research on low power wireless sensor and determine the working mode of duty cycle. According to the design requirements of the system, the architecture of the whole temperature measurement node and the design parameters of the chip are discussed in detail. After that, the design of digital circuit module and analog circuit module are introduced in detail, including digital controller, bandgap voltage difference circuit and temperature sensor. Analog to digital converter and so on. The design of the circuit through the corresponding digital circuit design tools and analog circuit design tools simulation test. The chip is designed in XFAB 0.35 渭 m process. The power consumption of the chip is 36.5 MW in wakeup mode. However, the average power consumption of the thermometer chip can be reduced to about 0.6 渭 W by using the duty cycle method. The chip can use self-extraction energy or battery power supply, the temperature measurement range is -20 鈩，
