technical field [0001] The invention relates to a D flip-flop, in particular to a three-value adiabatic D flip-flop and a four-digit three-value adiabatic synchronous reversible counter. Background technique [0002] In the VLSI of the existing deep submicron process, low power consumption and high packaging density have become important goals considered in chip design, and the research on low power consumption and high packaging density technology has become more and more important in integrated circuit design. field. A counter is an important functional device that constitutes a digital system. It can not only be used to count clock pulses, but also be used for frequency division, timing, generation of beat pulses and pulse sequences, and digital operations. Most of the traditional counters are powered by DC power supply, and its energy is always consumed at one time by power supply→capacitor→ground. While reducing power supply voltage and node capacitance can be used to...
