Through the research on working principle and structure of adder and adiabatic circuits

a design of ternary adiabatic adder was presented in this paper.First

the component-level function expressions of one bit ternary adiabatic full-adder were derived under the guidance of the theory of three essential circuit elements

and the corresponding circuit structure were realizing by using the bootstrapped NMOS FET

which enable the circuit to accomplish the energy injection and recovery.Then

the four bits ternary adiabatic adder was realized based on this circuit.Finally

PSPICE simulation results indicate that the proposed circuit has correct logic function and the obvious low power characteristics.
