1-Bit Full Adder

A full adder is comprised of 2 half adders and an OR gate. Ours is specially designed so that carry-in and carry-out are at the same height. This allows multiple full adders to be linked together.

The full adder is on the right. The handsome man on the left is Jeff. This photo was taken in the Academic Center at Olin.

This test shows what happens when the inputs are A=1, B=0 and Carry In=1.

1+0+1 = 10 which is a carry and no sum.
