Description

technical field [0001] The invention relates to a JKL flip-flop, in particular to a three-value low-power domino JKL flip-flop. Background technique [0002] Flip-flops are an important part of clock subsystems in sequential circuits, and are widely used in VLSIs that use high-performance clocks. Studies have shown that the power consumption of the clock subsystem is about 30-50% of the total power consumption of the circuit, so the research on low-power flip-flops is of great significance for reducing the power consumption of the clock subsystem and the total power consumption of the circuit. The adiabatic trigger using AC pulse power supply changes the irreversible energy conversion method of traditional circuits from electric energy to heat energy, fully recovers the charges stored in the internal nodes of the circuit, realizes energy recycling, and reduces the power consumption of the circuit. [0003] With the continuous progress of semiconductor technology, the propor...
