Logic Gate Diagram For Full Adder. The exclusive or gate is abbreviated as ex or gate or sometime as x or gate. It has n input n 2 and one output.
In a 32 bit ripple carry adder there are 32 full adders so the critical path worst case delay is 3 from input to carry in first adder 31 2 for carry propagation in latter adders 65 gate delays. One bit full adder with carry in and carry out ci a b q co. It has n input n 2 and one output.
Xor or ex or gate is a special type of gate.
A not or operation is known as nor operation. Two input xor gate two input and gate two input or gate forms the full adder logic circuit input output of this logic diagram can be derived by the following truth table. One bit full adder with carry in and carry out ci a b q co. The first half adder circuit is on the left side.
