Abstract:
A method of using memristor aided logic (MAGIC), comprises connecting together two input and one output memristor between a bit line and a word line, each memristor having a high resistance state and a low resistance state, setting the output memristor to the low resistance state as an initiation state and then applying logic inputs to the input memristors. The output then depends on whether the logic inputs have set the output memristor to the high resistance state.
Abstract:
The invention is a logic arrangement comprising a thermoconductive element (10) having two states according to its electric resistance and being switchable between the two states by a thermal energy amount, and a heating resistor (12', 12", 12"') being coupled by energy coupling to the thermoconductive element (10) and being adapted for generating thermal energy. In the logic arrangement, the heating resistor (12', 12", 12"') is a logic input (16', 16", 16"') of a logic level determined by the thermal energy amount thereon, and the thermoconductive element (10) is a logic output (14) of a logic level determined by the thermal energy amount thereon.
Abstract:
A dual-mode logic gate, for selectable operation in either of static and dynamic modes, includes: a static gate which includes at least one logic input and a logic output; a mode selector, configured for outputting a turn-off signal to select static mode operation and for outputting a dynamic clock signal to select dynamic mode operation; and a switching element associated with the mode selector static gate, comprising a first input connected to a constant voltage, a second input for inputting the mode selection signal from the mode selector, and an output connected to a logic output of the static gate. The switching elements switches the logic gate operation from static to dynamic mode, by applying the appropriate signal to the switching element.
Abstract:
In one or more embodiments described herein, there is provided an apparatus (200) comprising a substrate (201 ), and a plurality of carbon nanotubes (semiconducting nano-elements) disposed and fixed with said substrate (201 ). The nanotubes are disposed and fixed on said substrate such that they define a carbon nanotube network (202) substantially at the percolation threshold of the network. As the network (202) is at the percolation threshold, this provides for one or more signal paths extending from an input region (203b) to an output region (204b). The apparatus is configured to, upon receiving particular input signalling via the input region (203b), provide particular predefined output signalling at the output (204b) via the one or more signal paths, the particular output signalling being predefined according to the one or more one signal paths.

The first node is capacitive betweeen a first operating voltage tap and a second operating voltage tap. The gate electrode of the lone-electron transistor is connected to a control voltage tap. The circuit arrangement concerned is suited for the logical combination of binary numbers, the positions of which are recorded in the first and second main nodes.
Abstract:
Apparatus and associated methods relate to quasi-adiabatic logic gates in which at least one supply terminal receives sinusoidal power. The quasi-adiabatic logic gate is configured to perform a specific logic function operative upon one or more input signals. When the quasi-adiabatic logic gate switches the output from one logic state to another logic state, the transient switching portion of the output signal substantially tracks the sinusoidal supply signal. Such a sinusoidal transient switching portion of the signal has lower frequency components than have traditional CMOS logic gate transients. Some embodiments include an inductor through which the sinusoidal supply signal is provided to the quasi-adiabatic logic gate. Such an inductor can both provide charge to and recover charge from switching quasi-adiabatic logic gates, thereby further reducing power.

Embodiments include a logic gate system comprising a first micro-cantilever beam arranged in parallel to a second micro-cantilever beam in which a length of the first micro- cantilever beam is shorter than a length of the second micro-cantilever beam. The first micro-cantilever beam is adjacent to the second micro-cantilever beam and the first micro-cantilever beam is coupled to an input DC bias voltage source to the logic gate system. The second micro-cantilever beam is coupled to an input AC voltage signal that dynamically sets a logic operation of the logic gate system by at least changing an operating resonance frequency for one or more of the first micro-cantilever beam and the second micro-cantilever beam.
