Abstract :
A high speed parallel full adder is designed which can perform carry-free addition of two modified signed digit quaternary numbers. For digital implementation, the sign digit quaternary numbers are represented using 3-bit 2´s complement notation. The adder truth table with possible schemes of the electronic and optical implementation are provided
