[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，
