Design of Ternary Adiabatic Domino Adder on Switch-level

By researching the adiabatic domino circuit and the adder, a novel design of low power ternary adder on switch-level is proposed. First, the switch-level structure of ternary adders summing circuit and carrying circuit are derived according to the switch-signal theory and the peculiarity of adiabatic domino circuit. The design of the one bit adiabatic Domino adder unit and the four bit adder are obtained. Finally, the circuit is simulated by Spice tool and the results show that the logic function of the four bit adiabatic Domino adder is correct. The energy consumption of the four bit adiabatic Domino adder is 61% less than the conventional Domino counterpart.
