    A method for distributing capacitor and resistor area to optimally reduce die area in a given continuous-time filter design while maintaining the filter's designed signal-to-noise ratio (SNR), frequency response, and topology is discussed. To do this, a basic linear programming algorithm is developed from derived circuit cost and constraint functions. Among the three major filter types of fifth-or... View full abstract»

    It is well known that low noise amplification can be performed by using a capacitor whose capacitance can be controlled. In this paper, it is shown that changing the inversion level of a MOS transistor allows voltage amplification. The theoretical characterization of this amplifier in terms of gain and harmonic distortion is made, and comparisons with HSPICE results are performed. Finally, some pr... View full abstract»

    A fully integrated CMOS implementation of a continuous-time analog median filter is presented. The median filter uses two compact analog circuits as building blocks to implement the variable delay and median detection. Median detectors are based on current saturating transconductance comparators, while the time delay is implemented using first-order all-pass filters. Both circuits allow modular ex...

    This paper presents a scheme for the efficient implementation of a low supply voltage continuous-time high-performance CMOS current mirror with low input and output voltage requirements. This circuit combines a shunt input feedback and a regulated cascode output stage to achieve low input resistance and very high output resistance. It can be used as a high-precision current mirror in analog and mi... View full abstract»

  • A bandpass mismatch noise-shaping technique for Σ-Δ Modulators

    A simple bandpass mismatch noise-shaping technique for Σ-Δ modulators is presented. This technique uses the data-directed scrambler structure and achieves ∼20 dB improvement in signal-to-noise ratio (SNR) for an oversampling ratio (OSR) of 32. Compared to the technique of bandpass mismatch noise shaping of Lin and Schreier, here, the SNR is improved by ∼ 7dB resulting in a 1-bi... View full abstract»

  • Reduced-complexity transform-domain adaptive algorithm with selective coefficient update

    This paper proposes a new low-complexity transform-domain (TD) adaptive algorithm for acoustic echo cancellation. The algorithm is based on decomposing the long adaptive filter into smaller subfilters and employing the selective coefficient update (SCU) approach in each subfilter to reduce computational complexity. The resulting algorithm combines the fast converging characteristic of the TD decom... View full abstract»

  • Constrained Chebyshev design of FIR filters

    Publication Year: 2004, Page(s):143 - 146

    In many filter-design problems, additional constraints are often imposed on the optimal filter in the sense of, say, minimal Chebyshev error norm. Based on the characteristic properties of the optimal filter for the Chebyshev design with frequency equation constraints, a modified Remez (MRemez) algorithm is proposed in this paper. The central problem of this paper is the constrained Chebyshev desi... View full abstract»

  • A polynomial-operator-based DFIIt structure for IIR filters

    In this paper, based on a polynomial-operator approach, a new structure is derived. This structure is a generalization of the transposed direct-form II structures in the conventional shift operator and the prevailing delta operator. The use of polynomial operators provides more degrees of freedom to minimize the roundoff noise gain of the filter without increasing the implementation complexity. Nu... View full abstract»

  • An efficient VLSI design for a residue to binary converter for general balance moduli (2n-3,2n+1,2n-1,2n+3)

    In this paper, we present a new four-moduli set (2n-3,2n+1,2n-1,2n+3) and an efficient residue to binary (R/B) converter design. The merits of the proposed four-moduli set include 1) larger dynamic range; 2) higher degree of parallelism for conversion; 3) balanced bit-width for internal RNS arithmetic operations; and 4) flexible moduli set selection.
