Comparator with hysteresis

摘要

The invention relates to a comparator with hysteresis which can be adjusted with arbitrary accuracy within wide limits, consisting of a differential amplifier stage and an output stage transistor. The object of specifying such a comparator with low power consumption, which can be monolithically integrated, is achieved by the fact that the reference voltage is changed by the position of the output voltage in such a manner that an additional current is impressed in the reference voltage divider with the aid of a current source. <IMAGE>
