ABSTRACT:
In a prehcarge-type carry chained adder circuit, stages as represented by adders are grouped into a plurality of blocks each consisting of a plurality of stages. When the propagating functions of the stages of each block are active, a carry signal reproduced from the preceding block is transferred to the succeeding blocks through a bypass circuit.
