| Abstract: |
| This paper presents a new logarithmic function for response linearization of the thermistor thermometer.A theoretical study of the proposed scheme is presented.A novel and inexpensive circuit configuration for realizing the proposed logarithmic function is described.The proposed scheme offers linear temperature/voltage conversion over a wide dynamic range with an output is independent of fluctuations in the ambient temperature.Test results are given to support the theoretical conclusions. |
