英文摘要： Internet of things is the emerging industries of strategic importance that our country will advance.As the passive wireless temperature sensor based on electromagnetic energy harvesting has many merits such as wide application area, low cost, long life, small size, environment-friendly, high safety,it has important application value for internet of things. This project will adopt advanced design theories and design methods of RF/analog intergrated circuits,to study the two key technologies of the sensor chip. The first technology is the design of the energy harvesting circuits, and the second is the design of temperature sensor.In this project, the RF-DC/DC-DC voltage boosting technique will be applied to increase the energy conversion efficiency of the electromagnetic energy harvesting circuits, furthermore, Time to Digital Conversion/Analog to Digital Conversion techniques will be applied to realize ultra low power CMOS temperature sensor chip that can work using electomagnetic energy with proper temperature precision and can be adapted to wide power supply voltage. The research of the project will accumulate the key theories and experiences of the passive wireless temperature sensor that can work using electromagnetic energy.
