Linearization of thermistor resistance-temperature characteristics using active circuitry
R. K. Chakravarty, K. Slater, Christian-Herbert Fischer · Review of Scientific Instruments · 1977
A linear relationship is obtained between the temperature of a thermistor and the voltage output from an electronic circuit into which the thermistor is incorporated. The circuit is basically a combination of a logarithmic amplifier and an analog divider. It is capable of producing a linear voltage output with temperature for virtually all commercially used thermistors having resistance in the range of 3 MΩ–500 Ω.
