Description

technical field [0001] The invention relates to a D flip-flop, in particular to a four-value adiabatic dynamic D flip-flop. Background technique [0002] Multi-valued flip-flops are widely used sequential circuits in multi-valued logic systems. It not only reduces the number of input and output leads, reduces production costs, but also increases the information density of integrated circuits. Speed ​​up data processing. [0003] At present, the existing multi-valued flip-flops mainly use redundant suppression technology and double-edge trigger technology to increase the speed of multi-valued logic systems and reduce the power consumption of integrated circuits. However, these technologies still use the traditional CMOS circuit DC power supply mode, and the total energy It is converted from electrical energy to thermal energy in an irreversible form, and its power consumption savings are very limited. Therefore, the study of low-power multi-valued flip-flops has practical s...
