ABSTRACT:
The binary adder cell is provided for summing three input binary variables A, B and C and has a sum output S and a carry output R. The cell comprises a first complemented exclusive-OR gate receiving the input variables A and B and providing an intermediate variable F.sub.1 =A.sym.B, a second complemented exclusive-OR gate receiving the intermediate variable F.sub.1 and the input variable C and providing the sum output S, a third complemented exclusive-OR gate receiving the input variables A and C and providing an intermediate variable F.sub.3 =A.sym.C and a carry generating circuit for generating the carry output R from the two intermediate variables F.sub.1 and F.sub.3 and the sum output S. The gates and the carry generating circuit are designed with MOS transistors according to the same general structure.
