Abstract :
The proposed circuit represents an autoprogrammable voltage reference, the reduction of the temperature coefficient being achieved by the cumulative effect of two methods: autoprogrammable temperature stabilization of the chip and a superior-order curvature-correction technique. The originality of this work consists in implementing an automatic digital programmable loop designed to select, after the analysis of the thermal behavior of the chip, the optimal stabilization temperature and the optimal type of the curvature-correction. The simulated results report a temperature coefficient about 0.005 ppm/K.
