ABSTRACT:
Two currents that are to be compared are coupled to the two input terminals of a current mirror. The output is taken from a transistor stage which has its input coupled across the current mirror. In a balanced version the current mirror is made symmetrical and a balanced output pair is cross coupled across the current mirror, thus creating a fully symmetrical configuration.
