Hardware linearization of thermistor response using series-parallel resistors for temperature-to-time conversion

A scheme is suggested for obtaining linear temperature-to-time period conversion using series-parallel resistors with a thermistor. The circuitry presented for realizing the proposed converters possesses the advantage of easily adjustable sensitivity. An experimental temperature-to-time converter constructed for a standard thermistor provides an accuracy better than 0.1 K over the range 35-95°C. © 1994 IOP Publishing Ltd.
