We demonstrate the manipulation of transmitted light through an optical Fabry-Pérot cavity, built around a spectroscopy cell containing enriched rubidium vapor. Light resonant with the RbD2 (F = 2,F = 1) ↔ F ′ manifold is controlled by the transverse intersection of the cavity mode by another resonant light beam. The cavity transmission can be suppressed or enhanced depending on the coupling of...

Carbon-nanotube-based electronics offers significant potential as a nanoscale alternative to silicon-based devices for molecular electronics technologies. Here, we show evidence for a dramatic electrical switching behaviour in a Y-junction carbon-nanotube morphology. We observe an abrupt modulation of the current from an on- to an off-state, presumably mediated by defects and the topology of th...

In this paper a modified design of a sliding mode controller based on fuzzy logic for a soft switching sepic converter is introduced. Here a proportional integral (PI)-type current mode control is employed and a sliding mode controller is designed utilizing fuzzy algorithm. Sliding mode controller ensures robustness against all variations and fuzzy logic helps to reduce chattering phenomenon in...

An important category of such systems are those consisting of a continuous-time process to be controlled, a family of fixed-gain or variable-gain candidate controllers, and an “event-driven switching logic” called a supervisor whose job is to determine in real time which controller should be applied to the process. Examples of supervisory control systems include reconfigurable systems, fault co...

Dynamic logic circuits provide more compact designs with faster switching speeds and low power consumption compared with the other CMOS design styles. Domino logic overcomes the difficulties in dynamic circuits such as charge sharing and cascading. In this paper we are proposing a wide fan-in circuit with increased switching speed and noise immunity. Speed is achieved by quickly removing the ch...

ln this paper, the efficiency of a fully adiabatic logic circuit is compared with its combinational and pipelined static CMOS counterparts. The performance of each circuit is studied in terms of the maximum frequency of operation, the minimum voltage of operation, the circuit energy consumption, and the switching noise generated by the circuit. An 8-bit carry look-ahead adder is designed using ...

This paper proposes a transmitter system based on direct antenna amplitude-shift keying modulation for point-to-point microwave link. The proposed is formed from conventional microstrip and novel reconfigurable metasurface layer (RMSL). RMSL has two states: OFF (or Logic-0) ON Logic-1) where each switching scenario provides certain gain level. achieved through controlling the configuration to c...

Power optimization is one of the important challenges in VLSI circuit for testing engineers. Larger power dissipation becomes the reason for overheating and with every increase in 10oC in operating temperature, failure rates for the component on a chip doubles. Power dissipation is directly proportional to switching activities of the components on Integrated Circuits. Power optimization is poss...

Multiplexer’s square measure is a typical building block for data-paths, and is used extensively in a variety of applications together with the processors. In this paper authors have proposed a 4:1 multiplexer using PFAL and ECRL adiabatic logic design technique and compared with the Conventional CMOS Multiplexer. The basic approaches that we used for reducing energy/power dissipation in conven...

Nano-scale patterned techniques, DCpulsed-current-driven magnetization switching and spin-dependent transport properties of magnetic tunnel junctions (MTJs) are presented in this paper. The experiments show that the spin transfer torque (STT) plays a main switching role in the magnetization current switching and the current-induced circular magnetic field plays an assisted-switching role in the...
