Einen Komparator enthaltende elektronische Schaltung

Electronic circuit comprising a comparator

Circuit électronique comprenant un comparateur

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 (1) with an input (2), an output (4) and a reference input (3). To the reference input (3) a constant reference voltage (V ref ) is applied. The input voltage (V in ) to be compared with the reference voltage (V ref ) is superimposed to a time-dependent signal (8) and the resulting voltage is applied to the input (2) of the comparator (1).
