S. Kaliyugavaradan et al., APPLICATION OF RECIPROCAL TIME GENERATION TECHNIQUE TO DIGITAL TEMPERATURE-MEASUREMENT, IEEE transactions on instrumentation and measurement, 43(1), 1994, pp. 99-100
A thermistor-based temperature indicator is described, which produces
a parallel digital output proportional to absolute temperature, using
the principle of a reciprocal time generator. The instrument is suitab
le for fast measurement of temperature, with easy facility of range ad
justment. Temperature indication in degrees Celsius is also possible,
using additional simple circuitry. Experimental results are given in s
upport of the proposed method.
