Abstract :
A novel approach to reducing power dissipation in a thermistor probe for temperature/frequency converting circuit based on IC op-amp astable multivibrator is described. The output/input relation is linear over a wide temperature range with sensitivity 35 Hz/K. Experimental results are given to support the theoretical conclusions.
