Abstract
A simple designing method for linearizing circuits, based on one resistor, is presented. The errors caused by this circuit are calculated, considering the temperature range and the thermistor parameters. These errors are used as a basis for comparing the quality of active linearizing circuits. In many cases, complex circuits have similar errors to single resistor linearizing circuits. It is shown that the exponential approximation is one of the most important error sources. The authors propose to use more precise models. The relationship between the parameters of the exponential model and those of other models is discussed.
