| Abstract: | Design of an IC temperature transducer is described in this paper.A fundamental property of bipolar transistor is used to complete the temperature measurement,that the voltage drop between base electrode and emitting electrode is proportional to absolute temperature.The transducer has succeed in manufacturing in 6μm bipolar processing line.The circuit has 298.2μA output at 25°C with the maximum absolute error of ±3°C and the maximum nonlinear error of ±0.4°C in the working temperature range of -55°C～+150°C |
