This paper gives an overview of the work carried out during the course of the COST-266 action on circuit/wavelength switched network studies. Several subjects are discussed in detail in this paper. A first important topic deals with the different control plane models in singleand multi-domain networks. A second important issue is the routing and wavelength assignment problem, both in networks w...
The power consumption of a digital circuit can be reduced by decomposing it into sub circuits which can be turned off when inactive. Power can also be reduced by careful state encoding. Clock-gating techniques have been shown to be very effective in the reduction of the switching activity in sequential logic circuits. Modeling a given circuit as a finite-state machine, we formulate its decompos...
In hard-switched converters, the switching frequency is limited by switching losses and EMI problems. However, high-switching frequency is necessary to reduce the converter size. Hence, soft switching is imperative at high switching frequency to obtain good efficiency. Push–pull converter is a preferred topology at medium power level. This paper proposes a novel resonant transition topology for...
Abstract As the switching speeds and densities of Digital CMOS integrated circuits continue to increase, output switching noise becomes more of a problem. This paper reports a novel design technique which aids in the reduction of switching noise. The output driver stage is analyzed through the use of an equivalent RLC circuit. The results of the analysis are used in the design of an output driv...
A novel single-stage AC/DC converter is proposed in this letter. The converter is designed by integrating a sepic circuit and a flyback circuit, the circuit work in the quasi-resonance state, and the switch is turned on in the zero voltage switching (ZVS) state, which decreased the switching losses of the converter Streszczenie. Opisano nowy konwerter AC/DC. Układ pracuje w stanie quasi-rezonan...
In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...
Currently, traffic engineering means circuit or virtual circuit switched technology even in packet switched networks. The need for a simpler and more suitable device for IP networks is getting stronger. In this paper, we present a new architecture for IP layer traffic engineering called Core State Limited Load Sharing (CSLLS). Our solution is highly tunable between low complexity – low granular...
This paper introduces a framework for the design, synthesis and cycle-accurate simulation for parallel computing networks of 128+ processors. In order to accurately characterize the network, we present a bottom-up design methodology in which each of the components are designed using a hardware description language and synthesized to an FPGA for performance estimation of the final ASIC implement...
