    The concept of phase-domain fractional-N frequency synthesis is presented. Synthesizers using this architecture can achieve fast frequency switching without limiting the minimum channel spacing. In this architecture, a numerical phase comparator is used in conjunction with weighting coefficients, as a linear weighted phase-frequency detector. The synthesizer output spur level is determined by two ... View full abstract»

    Parallelism can be used to increase the conversion bandwidth of delta-sigma (ΔΣ) analog-to-digital converters (ADCs). Time-interleaved, parallel ΔΣ, and frequency-band-decomposition ADCs are three parallel architectures that are shown to be explained using the same underlying theory. This common structure is then used to explore the design tradeoffs among these architecture... View full abstract»

    An approach for the fast and accurate generation of compact distributed circuit models for on-chip transmission lines on lossy silicon substrates is presented. Using a novel ABCD matrix partitioning procedure, accurate distributed circuit models are extracted from scattering parameters obtained from measurements and calibrated full-wave electromagnetic simulations for a small set of transmission-l...

    Ring oscillators' phase noise, when their delay cells are modeled as buffers and the noise sources assumed to be thermal noise, has some distinctive characteristics. We investigate one of the distinct characteristics, the threshold crossing property. The resulting model is shown to arise from the last passage time behavior of thermal noise present in the circuits. Simulation results on ring oscill... View full abstract»

    The JPEG2000 image coding standard employs the biorthogonal 9/7 wavelet for lossy compression. The performance of a hardware implementation of the 9/7 filter bank depends on the accuracy and the efficiency with which the quantized filter coefficients are represented. A high-precision representation ensures compression performance close to the unquantized, infinite precision filter bank, but at the... View full abstract»

    A leakage-tolerant design technique for high fan-in dynamic logic circuits is presented. An NMOS transistor with gate and drain terminals tied together (diode) is added in series with the evaluation network of standard domino circuits. Due to the stacking effect, the leakage of the evaluation path significantly decreases, thereby improving the robustness of the circuit against deep-submicron subth... View full abstract»

    Convolutional codes are widely used in many communication systems due to their excellent error-control performance. High-speed Viterbi decoders for convolutional codes are of great interest for high-data-rate applications. In this paper, an improved most-significant-bit (MSB) -first bit-level pipelined add-compare select (ACS) unit structure is proposed. The ACS unit is the main bottleneck on the ...

  • Eliminating the fanout bottleneck in parallel long BCH encoders

    Long BCH codes can achieve about 0.6-dB additional coding gain over Reed-Solomon codes with similar code rate in long-haul optical communication systems. BCH encoders are conventionally implemented by a linear feedback shift register architecture. Encoders of long BCH codes may suffer from the effect of large fanout, which may reduce the achievable clock speed. The data rate requirement of optical... View full abstract»

    We consider hardware solutions to the adaptive-signal subspace-estimation problem. In deriving a hardware-realizable subspace tracking algorithm, we have applied delayed updating to the PASTd algorithm to achieve high speed. Pipelined and systolic architectures and the estimation of the dominant eigenvector or the signal subspace are also studied. Methods for approximating a reciprocal computation... View full abstract»

    This paper is intended to show a general method (inhibition method) that relies on the superposition principle to analyze linear systems and electric circuits, based on hierarchical sequences of more simple topologies with some inhibited elements and on a simple recollecting logic to calculate the final solution from the previous partial and more elementary solutions. The result of the analysis is... View full abstract»

    Large disturbances in power systems often initiate complex interactions between continuous dynamics and discrete events. The paper develops a hybrid automaton that describes such behavior. Hybrid systems can be modeled in a systematic way by a set of differential-algebraic equations, modified to incorporate impulse (state reset) action and constraint switching. This differential-algebraic impulsiv... View full abstract»

    Designing optimal perfect-reconstruction (PR) and near PR (NPR) cosine-modulated filter banks is essentially a constrained nonlinear minimization problem. This paper proposes two second-order cone-programming based algorithms for designing NPR and practically PR cosine-modulated filter banks with improved performance relative to several established design methods.

    The small-signal behavior of a frequency controlled resonant converter is modeled as an equivalent pulsewidth modulation (PWM) converter. By this model, a recently developed simulation algorithm for PWM converter is modified to simulate both the open-loop and closed-loop small-signal behavior. Experimental results show that this approach is accurate and efficient. View full abstract»

    This paper presents a fixed-point mean-square error (MSE) analysis of coordinate rotation digital computer (CORDIC) processors based on the variance propagation method, whereas the conventional approaches provide only the error bound which results in large discrepancy between the analysis and actual implementation. The MSE analysis is aimed at obtaining a more accurate analysis of digital signal p... View full abstract»

    Based on oversampling the system output, this paper presents a deterministic approach to blind identification of fast changing infinite-impulse-response (IIR) systems. The contributions of this paper are: 1) we prove that oversampling the output of a single-input-single-output (SISO) IIR system is equal to transforming the SISO IIR system into a single-input-multiple-output (SIMO) IIR model with a...

    The paper discusses the applicability of the piecewise-ellipsoidal approximation (PEA) to the acceptability region for solution of various design problems. The PEA technique, originally developed and tested for linear discrete circuits described in the frequency domain, is briefly reviewed. It is shown that PEA is a generic mathematical method and its applicability is extended to linear and nonlin... View full abstract»

    Fast analytical design procedures for finite impulse response (FIR) maximally flat (MF) and optimal equiripple (ER) notch filters are introduced. The closed form solution provides recursive computation of the impulse response coefficients of the filter. The ER FIR filters are optimal in the Chebyshev sense. The relation between the MF and ER notch filter is presented in order to emphasize the supe... View full abstract»
