Title: Adder
Inventor: SUZUKI YASOJI
IPC: G06F7/50
Filed: 1987-12-21
Abstract: PURPOSE:To reduce a high speed pattern area by replacing the transmission gate part of an adder circuit with the buffer of a clocked inverter constitution, giving driving ability to the part, and making unnecessary an inverter for driving. CONSTITUTION:MOS transistors (TR) 41-44 of a P channel and an N channel constitute a buffer of the clocked inverter constitution, and the propagation of a carry from a low-order is controlled. Since a carry line is surely buffered by the buffer consisting of the TRs 41-44 at every stage, when it is connected in a multistage way, inverters 11 and 12 of a carry input inserted to a carry input C0 at the lowest stage does not require the driving ability, it is unnecessary to be enlarged as a pattern, or it can be omitted. In addition, since the buffering is carried out at every stage, the propagation of the connected carry in the multistage way is not attenuated as it moves to the upper stages, and it is advantageous from the viewpoint of a speed. Thus, the adder with the small pattern area can be obtained at high speed.
