ABSTRACT:
A chain-type ripple-carry generating circuit having a plurality of cascaded stages is provided with a regeneration network in each stage for restoring the logic level of a carry signal propagating through the stage. In one embodiment of the invention the regeneration network is designed to restore a carry-not bit and comprises an MOS transistor having its conduction channel coupled between the input of the stage and a ground terminal, the gate of the transistor being driven by a two-input NOR gate, one input of the NOR gate being connected to receive a precharge clock signal and the other input being connected to the input of the stage. When the precharge clock signal is at a logic "0" level and the input of the stage receives a carry-not bit at a logic "0" level, the NOR gate drives the MOS transistor into conduction causing the input of the stage to be pulled to substantially ground potential.
