    An alternative architecture for instantaneous data recovery for burst-mode communication is introduced. The architecture can perform 1:n demultiplexing without additional clock recovery phase-locked loop or sampling blocks. A finite-state machine (FSM) is formed with combinational logic and analog LC transmission line delay cells in a feedback loop. The FSM responds to input data transitions insta...

    For multiple-model adaptive control systems, “multi-controller” architecture can be efficiently implemented (multirealized) by means of a “state-shared” parameter-dependent feedback system. Necessary and sufficient conditions for the multirealization of a family of linear multivariable systems based on matrix fractional descriptions are presented. The problem of the minimal...

    We model dc–dc power converters using the complementarity formalism. For each position of the switches, the dynamics is given by a linear complementarity system which incorporates, in a natural way, the description of generalized discontinuous conduction modes (GDCM), characterized by a reduction of the dimension of the effective dynamics. For systems with a single diode, analytical state-sp... View full abstract»

    Cosine modulated filter banks have gained popularity for their ability to provide perfect reconstruction (PR) while maintaining an efficient design and implementation. However, this effectiveness is hindered if the filter bank is implemented in the fixed-point domain where quantization, rounding, and overflow occur, and result in reconstruction errors. In this article we demonstrate how to maintai... View full abstract»

    With the ever-growing complexity of interconnect networks, models developed from measured data or data from 3-D electromagnetic simulators are increasingly becoming essential. It is to this end that the current contribution is directed. In particular, it focuses on the development of a model via a Fourier series expansion (FSE) approach. Its primary advantage is that the response in the time domai... View full abstract»

    In this paper, simple analog circuits to implement a repetitive control scheme are discussed. The repetitive control has shown to be a useful tool for tracking of periodic reference signals and for compensation of periodic disturbances. The main advantages of the proposed circuitry are: 1) no digital conversion required; 2) easy tuning to the corresponding frequency; and 3) cost effectiveness. A d... View full abstract»

    The passivity conditions for delayed neural networks (DNNs) are considered in this paper. We firstly derive the passivity condition for DNNs without uncertainties, and then extend the result to the case with time-varying parametric uncertainties. The proposed approach is based on a Lyapunov–Krasovskii functional construction. The passivity conditions are presented in terms of linear matrix i... View full abstract»

    The ridges obtained from chaotic signals can give the relevant information about the phase structures of the dynamical systems. Therefore, a new wavelet ridge determination method for the noisy signals and nonstationary signals, which is based on the singular value decomposition (SVD) has been proposed in this paper. The proposed method has been compared with Carmona method for monocomponent signa... View full abstract»

    Leakage power reduction is extremely important in the design of scaled CMOS logic circuits. The dominant leakage components of such circuits are the subthreshold leakage and the thin-oxide gate leakage. This paper describes an efficient leakage reduction method that considers both these components, and is based on the selective insertion of control points. The selection is based on the leakage red... View full abstract»

    In this paper, a new error-compensation network for fixed-width multipliers is proposed. The error-compensation block is composed of two summation trees which are optimally chosen in order to minimize either the mean-square error or the maximum absolute error. The new technique substantially improves error performances with respect to previously proposed approaches. Simulation results show that ne... View full abstract»

    A novel low-power and small-area digital I/O cell is proposed in this work. The new input/output (I/O) cell drastically reduces the I/O power consumption, which has been considered as the major power dissipation of the whole chip. The maximum operating clock is 500 MHz given a 10-pF offchip load. On top of the power saving feature, the proposed cell occupies merely 10535.2=4167.45 (transmitter)+63... View full abstract»
