    A scheme for achieving adaptive reduction in the order of the loop filter of usual high-order, single-stage, single-bit Delta-Sigma (ΔΣ) modulators is proposed in order to improve their performance. The resulting ΔΣ modulators can recover from instability effectively, having also an extended input signal range in comparison to that of the corresponding conventional Δ&... View full abstract»

    In this paper, we first introduce a straightforward asynchronous shift register design implemented by differential cascode voltage switch logic and micropipeline. The corresponding latency defect between data readout is then described. To solve this problem, we propose a new architecture for the design. Finally, a basic building block with respect to our architecture is proposed. View full abstract»

    The preservation of some control-oriented positive real properties (passivity, positivity, bounded realness, as well as input-output behavior) in multi-input multi-output transfer functions is studied, when performing substitutions (of the complex Laplace variable s) by a particular class of rational strictly positive real (SPR) functions, the so-called SPR functions of zero relative degree (SPR0 ...

  • Corner block list representation and its application to floorplan optimization

    We propose to use a corner block list (CBL) representation for mosaic floorplans. In a mosaic floorplan, each room has only one block assigned to it. Thus, there is a unique corner room on the top right corner of the chip. Corner block deletion and corner block insertion keep the floorplan mosaic. Through a recursive deletion process, a mosaic floorplan can be converted to a representation that is... View full abstract»

  • An accelerated decomposition algorithm for robust support vector Machines

    This paper proposes an accelerated decomposition algorithm for the robust support vector machine (SVM). Robust SVM aims at solving the overfitting problem when there is outlier in the training data set, which makes the decision surface less contoured and results in sparse support vectors. Training of the robust SVM leads to a quadratic optimization problem with bound and linear constraint. Osuna p... View full abstract»

  • Low-voltage-swing monolithic dc-dc conversion

    A low-voltage-swing MOSFET gate drive technique is proposed in this paper for enhancing the efficiency characteristics of high-frequency-switching dc-dc converters. The parasitic power dissipation of a dc-dc converter is reduced by lowering the voltage swing of the power transistor gate drivers. A comprehensive circuit model of the parasitic impedances of a monolithic buck converter is presented. ... View full abstract»

  • Effect of CFOA nonidealities in Miller integrator cells

    The performance of the Miller integrator cells based on current feedback OpAmps (CFOAs) is evaluated. Inverting and noninverting structures are analyzed and compared to traditional implementations using voltage OpAmps (VOAs). Fundamental relations, useful for design purposes, are also carried out. CFOA-based implementations were found to exhibit lower dc gain and higher relative error in the unity... View full abstract»

  • An I/Q mismatch-free switched-capacitor complex sigma-delta Modulator

    This paper presents a technique to suppress the mismatch between the in-phase (I) and quadrature-phase (Q) channels of a switched-capacitor complex sigma-delta modulator that is used for the analog-to-digital conversion of a real intermediate-frequency radio signal. The mismatch is suppressed through time sharing of the critical capacitors, i.e., the input sampling capacitor and the capacitor of t... View full abstract»

  • New compact CMOS continuous-time low-Voltage analog rank-order filter architecture

    A new compact CMOS continuous-time analog rank-order filter topology is presented. The hardware complexity grows linearly with the number of inputs at the rate of only two transistors per input. The implementation is based on a multiple input differential structure. The rank is programmable with the tail current source for all rank-order values from the Min to the Max case. The circuit has low vol... View full abstract»

  • Exponential filtering for uncertain Markovian jump time-delay systems with nonlinear disturbances

    In this paper, we study the robust exponential filter design problem for a class of uncertain time-delay systems with both Markovian jumping parameters and nonlinear disturbances. The jumping parameters considered here are generated from a continuous-time discrete-state homogeneous Markov process, and the parameter uncertainties appearing in the state and output equations are real, time dependent,...

    This work describes a 10-b multibit-per-stage pipelined CMOS analog-to-digital converter (ADC) incorporating the merged-capacitor switching (MCS) technique. The proposed MCS technique improves the signal processing speed and resolution of the ADC by reducing the required number of unit capacitors by half in comparison to a conventional ADC. The ADC resolution based on the proposed MCS technique ca... View full abstract»
