Embodiment 1
[0035] Embodiment 1: According to the logical relationship to be realized by the circuit, the truth table of the three-valued adiabatic D flip-flop with reset and set terminals can be obtained, as shown in Table 1.

[0037]
[0038]The present invention combines "Design of a DTCTGAL circuit and its application" disclosed in the Chinese Journal of Semiconductors on the basis of analyzing the truth table of Table 1 (authors: Wang Pengjun, Li Kunpeng, and Mei Fengna) [Journal of Semiconductors, "Based on DTCTGAL circuit design and application of dual-power clock", Wang Pengjun, Li Kunpeng, Mei Fengna], design a three-valued adiabatic D flip-flop: first use the clock to control the clock The controlled NMOS tube is used for the reset signal R, the set signal S, the input signal D, and the complementary reset signal complementary set signal and complementary input signals...
Embodiment 2
[0043] Embodiment 2: Since the three-value adiabatic D flip-flop only has the function of memorizing three-value data, and does not have the function of directly counting three values of input pulses, the synchronous reversible counter should also have the function of counting down. From the definition of anti-circulation operator in Post algebra, it can be seen that anti-circulation gate has a decrement function.
[0044] x ← =(X-1) mod 3
[0045] Among them, X, X ← are the input and output of the reverse loop gate, respectively. According to the logical relationship to be realized by the circuit, the truth table of the three-valued adiabatic reverse cycle gate can be obtained, as shown in Table 2, where in, is the complementary input signal, out, are complementary output signals.
