AB flip-flop, a first step to multilevel sequential logic

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.
