Design of ternary flip-flops and sequential circuits based uponU hgate

According to the next-state equations of various ternary flip-flops (tri-flop), which are based upon ternary modular algebra, various ternary flip-flops are implemented by using universal-logic-modules,U _hs. Based on it ternary sequential circuits are implemented by using array of universal-logic-modules,U _hs. Supported by the National Natural Science Foundation of Zhejiang Province, China.
