    摘要: Disclosed are a latch circuit and method for preventing double node upsets (DNUs). A first, second, and third storage circuit, each comprising four inputs and an output, are electrically interconnected with a first and second three-input c-element circuit, each comprising three inputs and an output, and a two-input c-element circuit comprising two inputs and an output. The output of the first storage circuit is connected to a first input of the first three-input c-element circuit, a first input of the third storage circuit and a third input of the second storage circuit. The output of the second storage circuit is connected to a second input of the first three-input c-element circuit, a first input of the two-input c-element circuit, and a second input of the second three-input c-element circuit. The output of the third storage circuit is connected to a second input of the two-input c-element circuit, a third input of the first three-input c-element circuit and a third input of the second three-input c-element circuit.

    摘要: A dual-gate transistor having a negative differential resistance (NDR) region is disclosed. The dual-gate transistor includes a back-gate, a zero-bandgap graphene layer disposed on the back-gate, a top-gate disposed on a portion of the zero-bandgap graphene layer adjacent to the top-gate, and a drain disposed on a portion of the zero-bandgap graphene layer adjacent to the top-gate and displaced from the source. Also included is a dynamic bias controller configured to simultaneously sweep a source-drain voltage and a top-gate voltage across a Dirac point to provide operation within the NDR region. Operation within the NDR region is employed to realize non-Boolean logic functions. Graphene-based non-Boolean logic circuits are constructed from pluralities of the disclosed dual-gate transistor. Pattern recognition circuitry for operation between 100 GHz and 500 GHz is also disclosed via the graphene-based non-Boolean logic circuits.
