  • Method for linearizing the characteristic curve of an electronic component and an apparatus for implementing the same
    Patent number: 4132116
    Abstract: A method for linearizing the exponential characteristic curve of an electronic component, in particular the temperature/resistance characteristic of a thermistor is provided. The output value of the component is compared with the output value of a reference circuit varying exponentially in time and in the same sense as said characteristic, and the time interval is measured between a fixed starting moment, at which the exponential variation is already taking place, and the moment when the two output values become equal.
