A novel voltage output integrated circuit temperature sensor

         

摘要

The novel integrated circuit(IC) temperature sensor presented in this paper works similarly as a two-terminal Zener,has breakdown voltage directly proportional to Kelvin temperature at 10mV/℃,with typical error of less tha ±1.0℃ over a temperature range from-50℃to +120℃ .In addition to all the features that conventional IC temperature sensors have,the new device also has very low static power dissipation(0.5mW),low output impedance(less than 1Ω),execllent stability,high reproducibility,and high precision.The sensor's circuit design and layout are discussed in detail.Applications of the sensor include almost and type of temperature sensing over the range of -50℃-+125℃。The low impedance and linear output of the device make interfacing the readout or control circuitry especially easy.Due to the excellent performance and low cost of this sensor.more application of the sensor over wide temperature range are expected.
