By overcoming speed bottlenecks from electronic switching as well as optical/electronic conversions, all-optical logic gates can permit further exploitation of the nearly 40THz of bandwidth available from optical fibers. We focus on the use of optical solitons and alloptical logic gates to implement ultrafast "interchanges" or switching nodes on packet networks with speeds of 100Gbit/s or great...

Model-checking is becoming very popular for automated reasoning about hardware and software. The input can be in any language provided there is a translation to transition systems or Kripke structures; properties are then expressed in a temporal logic. Telephone switching systems are concurrent systems which are naturally described by a composition of interacting nite automata. We describe a mo...

Coherent manipulation of spin ensembles is a key issue in the development of spintronics. In particular, multivalued spin switching may lead to new schemes of logic gating and memories. This phenomenon has been studied with atom vapours 30 years ago, but is still awaited in the solid state. Here, we demonstrate spin multistability with microcavity polaritons in a trap. Owing to the spinor natur...

This paper considers the problem of estimating the power consumption at logic and register transfer levels of design from an information theoretical point of view. In particular, it is demonstrated that the average switching activity in the circuit can be calculated using either entropy or informational energy averages. For control circuits and random logic, the output entropy (informational en...

This work deals with design, modeling and simulation of the PI & the Fuzzy controlled DAB DC to DC converter systems. Open loop system is simulated with step change in input voltage. The output voltage in closed loop system is regulated using PI and Fuzzy controllers. The response of these two systems are compared. This converter has advantages like low EMI,less switching loss and improved dyna...

The experimental three-level system modeling technique discussed in this paper can be used during the design stage of a system for identifying mismatches among the architectural, microprogramming, and hardware logic levels. Compatible switching between modeling levels is emphasized. Execution of an application program by the architectural and microprogramming level models with switching between...

Field-Free Switching In article number 2112561, Jung-Il Hong, Chanyong Hwang, and co-workers demonstrate field-free spin-orbit torque switching of perpendicular magnetization in amorphous ferrimagnetic Gd/Co multilayers accompanied by a tilted magnetic anisotropy axis. This could facilitate the development memory logic devices without need for external application global field or manufacturing ...

The importance of on-chip power-rail inductance in generating delta-I power-supply noise is examined in this paper using systematic circuit simulation of the complete integratedcircuit power net. This source of noise is compared to the resistive IR drop in the net, and to the delta-I noise due to both high-inductanceand low-inductance-bonding packages. Results are presented for a typical on-chi...

We investigated copper as a working material for metallic atomic-scale transistors and confirmed that copper atomic-scale transistors can be fabricated and operated electrochemically in a copper electrolyte (CuSO4 + H2SO4) in bi-distilled water under ambient conditions with three microelectrodes (source, drain and gate). The electrochemical switching-on potential of the atomic-scale transistor ...
