ABSTRACT:
This invention relates to the operation of common electronic comparators and particularly to an electronic circuit with a comparator for the operational test of integrated circuits (ICs). According to the invention, the electronic circuit comprises a common comparator with an input, an output and a reference input. To the reference input a constant reference voltage is applied. The input voltage to be compared with the reference voltage is superimposed to a time-dependent signal and the resulting voltage is applied to the input of the comparator.
