摘要：
A method and a respective circuit arrangement capable of markedly limiting the absorption of current by a current comparator circuit. The invention consists in limiting the absorption of current through the branch of the comparator circuit, along which is forced the highest current to the value of the lowest current, which is in turn forced through the other branch of the comparator circuit. This condition is obtained without interfering in any way with other characteristics of switching speed and sensitivity of the comparator circuit.
