Pengjun Wang · JOURNAL OF SHENZHEN UNIVERSITY SCIENCE AND ENGINEERING · 2011
A design scheme of quaternary adiabatic dynamic D flip-flop was proposed.The analysis of adiabatic circuits and multiple-value flip-flops was presented.The multi-threshold metal oxide semiconductor(MOS) control technology and the switch-signal theory were used in this proposed scheme.Firstly a literal operation circuit structure of the quaternary adiabatic dynamic D flip-flop was derived.Then the generated logic signal was used to implement the quaternary output of the dynamic D flip-flop and to design a quaternary adiabatic loop operation circuit with memory function.The Pspice simulation results have verified that the designed circuits have correct logic functions.The proposed circuits can save about 90% energy at 55.6 MHz frequency compared to conventional complementary metal oxide semiconductor(CMOS) quaternary dynamic D flip-flop.
