    Mismatching and clock-feedthrough are sources of error in Switched-Current (SI) circuits producing DC offset, gain errors, and harmonic distortion, which cause deviations in SI filter responses in both the passband and the stopband. This paper develops formulas including these effects in the input-output description of filter building blocks to make possible not only a faster prediction of the fil... View full abstract»

    In this paper, the least-square design problem of a general two-dimensional (2-D) linear-phase FIR filter with an arbitrary magnitude response is studied. By minimizing the frequency-domain error function and exploiting some of the properties of the functions and matrices associated with the design problem, a novel closed-form solution is developed. The solution is expressed in terms of the desire... View full abstract»

    The recursive least square lattice (LSL) algorithm based on the newly developed scaled tangent rotations (STAR) is derived. Similar to other recursive least square lattice algorithms for adaptive filtering, this algorithm requires only O(N) operations. This algorithm also preserves the desired properties of the STAR recursive least square (STAR-RLS) algorithm. Specifically, it can be pipelined at ... View full abstract»

  • Statistically optimum pre- and postfiltering in quantization

    We consider the optimization of pre- and postfilters surrounding a quantization system. The goal is to optimize the filters such that the mean square error is minimized under the key constraint that the quantization noise variance is directly proportional to the variance of the quantization system input. Unlike some previous work, the postfilter is not restricted to be the inverse of the prefilter... View full abstract»

    Bias optimization is one of the most important design issues in many low power applications. Several biasing schemes for switched capacitor applications are analyzed in this paper from the settling time point of view. A bias circuit is described that provides the best tradeoff between the slew-rate and the unity gain bandwidth of a single dominant-pole opamp over process and temperature variations...

  • Linear associative memories with optimal rejection to colored input noise

    It is known that many linear associative memories are sensitive to input noise. To reduce such noise sensitivity, an approach of designing an optimal-noise-rejection linear associative matrix is presented in this paper. An optimally biased, as well as unbiased solution, in the sense of least-mean-square of recall error for colored input noise, is given. The theoretical lower bound of error for bia...

    The author develops two algorithms for the order reduction of two-dimensional (2-D) FIR digital filters, which lead to two indirect design methods. Specifically, it is shown how an optimal L2 design can be derived as a matrix approximation problem in the Frohenius norm, and how a suboptimal L design can he obtained by solving a matrix approximation problem in the 2-nor...

    Adaptive fault tolerance (AFT) is introduced and applied to finite impulse response (FIR) adaptive filters, Fault-tolerant adaptive filters (FTAFs) that result from using the principles of AFT are analyzed with respect to convergence rate, computational complexity, and hardware overhead. A practical and useful FTAF based on the discrete Fourier transform (DFT) is developed that can tolerate numero... View full abstract»
