Abstract
A technique for measuring temperature by a thermistor sensor which technique provides for a linearization of the temperature sensed by the thermistor by utilizing circuitry which responds to the thermistor and produces an output which is an exponential function of the temperature sensed by the thermistor. A further circuit, such as a logarithmic amplifier, responds to such output to provide a signal which represents the temperature.
