  • Design of a family of stable causal perfect-reconstruction IIR uniform DFT filter banks with good numerical properties

    Publication Year: 1999, Page(s):1518 - 1522

    A family of stable causal perfect reconstruction (PR) infinite-impulse response (IIR) discrete Fourier transform filter banks is presented, where a tradeoff between frequency selectivity and numerical properties is made. Some multipliers in both the analysis and synthesis filters could be made powers or sums of powers of two, in particular for feedback loops. Moreover, a simple scaling procedure t...

  • Bandpass filtering using quadrature modulation

    Publication Year: 1999, Page(s):1516 - 1518

    Existing quadrature-modulation systems for bandpass filtering do not make the bandpass filter response have a strictly linear-phase characteristic, even when the equivalent low-pass filter used in the system has a strictly linear-phase response. Simple modifications are proposed to make the bandpass response have a strictly linear-phase characteristic. The modified technique is then extended to ob... View full abstract»

  • Performing arithmetic functions with the Chinese abacus approach

    -This brief introduces a novel (or ancient) technique for highspeed arithmetic. The new proposed method is based on the still-used Chinese abacus. We show that proper electronic circuits, based on pass transistor and domino logic, allow us to achieve the same functions of the Chinese abacus. Simulations with a 0.35-μm CMOS technology show that either a pipeline 8-bit adder and 8×8 multipl... View full abstract»

  • PN code generator with low delay-power product for spread-spectrum communication systems

    We illustrate the low-power advantages of the One-Hot Residue Number System by presenting a pseudonoise (PN) code generator for battery-powered spread-spectrum communication systems. It exhibits a significantly reduced delay-power product below an equivalent binary number system implementation. This advantage is obtained because the number system allows the decomposition into small serially enable... View full abstract»

  • Structure and design of two-channel filter banks derived from a triplet of halfband filters

    A novel approach for the construction of two-channel one-dimensional (1-D) biorthogonal filter banks is described. This approach is intended to help overcome limitations in an otherwise effective set of recently proposed techniques while retaining the advantages of a simple design and feature-rich structure. The novelty of the method rests on the use of a triplet of halfband fillers, which are com... View full abstract»

  • Non-stationary noise responses of some fully differential on-chip readout circuits suitable for CMOS image sensors

    Cited by:  Papers (12)

    CMOS active-pixel image sensors, as well as charge-coupled devices, generate both white noise and 1/fα-noise over several decades depending on biasing current, operating temperature, and the characteristics of the process used, limiting the detector dynamic range. Three readout circuits, based on a fully differential cascode operational transconductance amplifier, designed and rea... View full abstract»

  • Minimax filters for microphone arrays

    Publication Year: 1999, Page(s):1522 - 1524
    Cited by:  Papers (21)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (224 KB)

    Conventionally, minimax spatial/spectral filters for microphone arrays are designed by first discretizing the spatial and frequency domains into a finite number of grid points and then performing the optimization over these points. The drawback with this approach is that the response of the spatial/spectral filters in between the grid points can be poor. More recently, an approach that performs th... View full abstract»

  • Nonstationary signal classification using pseudo power signatures: The matrix SVD approach

    This paper deals with the problem of classification of nonstationary signals using signatures which are essentially independent of the signal length. This independence is a requirement in common classification problems like stratigraphic analysis, which was a motivation for this research. We achieve this objective by developing the notion of an approximation to the continuous wavelet transform, wh... View full abstract»

    A multivariate polynomial matrix factorization algorithm is introduced and discussed. This algorithm and another algorithm for computing a globally minimal generating matrix of the syzygy of solutions associated with a polynomial matrix are both associated with a zero-coprimeness constraint that characterizes perfect-reconstruction filter banks. Generalizations, as well as limitations of recent re... View full abstract»

  • Signal-adapted recursive interpolating wavelet packets

    In this work, recursive interpolating wavelet packets with shape parameter vectors are constructed and the parameter-adaptive decomposition algorithms are presented, which are based on the subband coding gain. Unlike the previous structure-adaptive one in which every node employs the same pair of filters, the shape parameter vectors of every node are signal-adaptively selected in our approaches, t...

  • An innovative modelization of loss mechanism in silicon integrated inductors

    In this paper, we present an improved lumped-element equivalent circuit of silicon integrated inductors, which accurately takes into account parasitic effects and separately models the effect of metal and substrate losses. We describe an efficient procedure to deduce all the elements of the equivalent circuit from wideband, two-port measurements of the S-parameters of the inductor. The separate ch...
