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