Xuesong Zheng, Pengjun Wang, Qiankun Yang · International Conference on Electronics, Communications and Control · 2012
Through the research of multi-valued comparator, adiabatic circuit and dual-rail domino circuit, a design scheme of a ternary adiabatic dual-rail domino comparator was proposed. This scheme applied adiabatic technology to domino circuit and used dual-rail logic to eliminate the literal operation circuits. The switch-level expressions and circuit structures of one bit ternary adiabatic dual-rail domino comparator were realized by switch-signal theory, then, the four bits ternary adiabatic dual-rail domino comparator was realized on this circuit. HSPICE simulation results validated that the comparator has correct logic function, compared with the conventional ternary domino comparator, the energy saving can be achieved about 71.4%.
