Abstract:
1. A semiconductor integrated circuit device comprising: a first circuit block connected to a first node; a second circuit block connected to a second node; and a comparator to compare the first potential of the first node and a second potential of the second node, wherein the second circuit block is provided on the same semiconductor chip as the first circuit block, wherein a first supply current in a quiescent state flows through the first node and the first circuit block, and wherein a second supply current in a quiescent state flows through the second node and the second circuit blocks, a third node; a first MOS transistor of a first conductivity type having a source-drain path between the first node and the third node; and a second MOS transistor of the first conductivity type having a source-drain path between the second node and the third node, wherein a gate of the first MOS transistor is connected to a gate of the second MOS transistor, and wherein a gate of the second MOS transistor is connected to a drain of the second MOS transistor.
