通过对绝热多米诺电路和加法器的研究，该文提出一种新颖低功耗三值加法器的开关级设计方案。该方案首先利用开关-信号理论，结合绝热多米诺电路结构特点，推导出三值加法器本位和电路与进位电路的开关级结构式，由此得到一位三值加法器单元电路；然后通过单元电路的级联得到四位三值绝热多米诺加法器；最后，利用Spice软件对所设计的电路进行模拟，结果显示所设计的四位三值绝热多米诺加法器具有正确的逻辑功能，与四位常规多米诺三值加法器相比，能耗节省约61%。

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.
