D flip flop is one of the fundamental building blocks in most digital designs. Many high speed digital circuits such as memory require high speed and low power consumption. In existing method, the charge keeper is used to provide strong 0 and strong 1 since it uses pass transistor for signal feed through technique. A new D Flip Flop is proposed with signal feed through technique using transmiss...

A 10-bit low power track-and-hold (T&H) circuit aimed for the front-end of a pipelined analog-to-digital (A/D) converter has been designed. The T&H is sampling at 80MS/s, has a 30MHz analog bandwidth and was designed in a 0.18μm CMOS process with a supply voltage of 1.8 Volt. A switched capacitor topology applying correlated double sampling is used for the T&H circuit and the amplifier is a fol...

In this paper a low power and low area array multiplier with carry save adder is proposed. The proposed adder eliminates the final addition stage of the multiplier than the conventional parallel array multiplier. The conventional and proposed multiplier both are synthesized with 16-T full adder. Among Transmission Gate, Transmission Function Adder, 14-T, 16-T full adder shows energy efficiency....

moving towards nanometer scales, quantum-dot cellular automata (qca) technology emerged as a novel solution, which can be a suitable replacement for complementary metal-oxide-semiconductor (cmos) technology. the 3-input majority function and inverter gate are fundamental gates in the qca technology, which all logical functions are produced based on them. like cmos technology, making the basic c...

Increasing power dissipation has become a major constraint for future performance gains in the design of microprocessors. In this paper, we present the circuit design of an issue queue for a superscalar processor that leverages transmission gate insertion to provide dynamic low-cost configurability of size and speed. A novel circuit structure dynamically gathers statistics of issue queue activi...

Voltage Source Converters (VSC) have for the first time been used for HVDC transmission in a real network. Experience from the design and commissioning of the transmission shows that the technology has now reached the stage where it is possible to build high voltage converters utilising Insulated Gate Bipolar Transistors (IGBTs). Operation and system tests have proved that the properties that h...

We present plasmonic devices, consisting of periodic arrays of graphene nanoribbons (GNRs) and a graphene sheet waveguide, to achieve controllable plasmon-induced transparency (PIT) by numerical simulation. We analyze the bright and dark elements of the GNRs and graphene-sheet waveguide structure. Results show that applying the gate voltage can electrically tune the PIT spectrum. Adjusting the ...

Thalamic input to the neocortex is crucial for sensory perception and constitutes the basis of complex awake behavior. Connections within the neocortex play an important role in internally generated neural activity, which is considered critical for memory retrieval and for the generation of imagery in our dreams. Modulatory neurotransmitters, such as noradrenaline and acetylcholine, gate inform...

Due to technology scaling, devices are getting smaller, faster and operating at lower voltages. The reduced nodal capacitances and supply voltages coupled with more dense and larger chips are increasing soft errors and making them an important design constraint. As designers aggressively address the excessive power consumption problem that is considered as a major design limiter they need to be...

We propose a low-power redundant flip-flop to be operated with high reliability over 1GHz clock frequency based on the low-power ACFF and the highly-reliable BCDMR FF. Its power dissipation is almost equivalent to transmission gate FFs at 10% data activity while paying 3x area penalty. Experiments by α-particle and neutron irradiation reveals its highly-reliable operations with no errors at 1.2...
