Design of a 0.8V Low Power CMOS Temperature Sensor for RFID-based Train Axle Temperature Measurement

摘要：

A novel CMOS temperature sensor embedded in a passive UHF RFID tag is presented. The sensor consists of a temperature-to-current converter, two current-starved ring oscillators and two digital counters. High power consumption band-gap voltage references and traditional ADCs are not used for low power design. Post-layout simulation show that the power consumption is 0.64uW with a supply voltage of 0.8V at room temperature (27 ℃), and the conversion rate is up to 1 kHz. The average temperature resolution is 0.2℃/LSB from -40℃~120℃. The sensor is implemented in CMOS 0.18um and the core occupies an area of 0.09 mm2.
