An universal logic-circuit with flip flop circuit based on DG-CNTFET

In this paper, we propose the method for embedding the latch and the flip flop (FF) circuit to the universal logic circuit of Double Gate Carbon NanoTube Field Effect Transistor (DG-CNTFET) proposed in the previous work. Previously, 2-inputs universal logic circuit by 8 DG-CNTFET was proposed. If the embedding of flip flop to them is possible, the reconfigurable circuit which includes a state such as flip flop can be realized. The result of our research shows that SR-latch and D-latch with 3-inputs/state can be embedded within 2-inputs universal logic circuit. Thus it is shown that a D-FF can be embedded to two 2-inputs universal logic circuit.
