Although it promises many advantages, such as simpler circuits, fewer interconnections, small chip area, etc., unfortunately multilevel logic circuits have not received sufficient attention, because there is not sufficient hardware available. In particular, it is very difficult to find circuits to implement the multilevel sequential circuits. Presented is a new flip-flop circuit which is the basic building block of multilevel sequential circuits. It is shown that basic sequential circuits such as multilevel counter/dividers may be built using this circuit.

Abstract-Multilevel logic circuits has advantages of simpler circuit complexity, less interconnections and small chip area. However it has not found enough attention and applications because there is not sufficient hardware available. Reference [1] proposes a multilevel flip-flop circuit and its applications for building counter circuits. In this paper it is shown that it is possible to design any arbitrary sequential logic circuit by using this flip-flop. The multilevel circuit is simpler and uses fewer transistors compared to the binary equivalent circuit.  Index Terms-multivalued logic, sequential logic, multivalued flip-flop, current mode CMOS logic
