Abstract
An electronic comparator device with hysteresis, being of a type which comprises a differential cell having a signal input, an output, and a threshold input, further comprises a second differential cell having one input connected to said output and the other input connected to a controlling circuit portion which has an output connected to the threshold input to reduce the threshold voltage value stepwise on the first change-over of the output of the comparator.
