Abstract
A scheme using an analog multiplier that provides an output voltage linearly proportional to the absolute temperature over a wide dynamic range is presented. It has the advantage of being simple and attractive in that the calibration of the output indicating meter does not depend upon the thermistor parameters. Results of measurements in the range 283-493 K are presented. The deviation from the straight-line response amounts to an error of 6% at 283 K and decreases to about 0.6% at 320 K
