    The frequency-response masking approach for highspeed recursive infinite-impulse response (IIR) digital filters is introduced. In this approach, the overall filter consists of a periodic model filter, its power-complementary periodic filter, and two masking filters. The model filters are composed of two all-pass filters in parallel, whereas the masking filters are linear-phase finite-impulse respo... View full abstract»

    This paper presents the reverse jacket transform [RJT] and a simple decomposition of its matrix, which is used to develop a fast algorithm for the RJT. The matrix decomposition is of the form of the matrix products of Hadamard matrices and successively lower order coefficient matrices. This decomposition very clearly leads to a block circular sparse matrix factorization of the reverse jacket [RJ]<... View full abstract»

    An MPEG-2 audio decoding processor core is described with a focus on inverse quantization (IQ) and multichannel processing (MC) of Layer I and II decoding. A novel architecture that we propose can perform IQ at a high throughput. In addition, different types of dematrixing modes for MC process in the MPEG-2 standard can also be performed. The processor core is implemented and controlled with a ded... View full abstract»

  • SPICE simulation and tradeoffs of CMOS LNA performance with source-degeneration inductor

    Publication Year: 2000, Page(s):62 - 65

    In this brief, we study the tradeoffs of CMOS low noise amplifiers using source-degeneration inductor with both experimental data and simulation data. SPICE models based on the quasistatic (QS) assumption ignores the channel resistance and leads designers to overly rely on source-degeneration inductance. The non-QS model is much better. Source inductor adversely affects noise and gain. The parasit... View full abstract»

    Analysis of a physical model for spiral inductors on silicon leads to the conductor trace width that maximizes the quality factor at a given frequency. The simplicity of the physical model enables a computational procedure for efficiently optimizing the inductor quality factor and self-resonant frequency View full abstract»

    Resistance-capacitance (RC) sequence asymmetric polyphase networks have recently gained a renewed interest in the design of radio-frequency integrated transceivers. These networks provide an efficient way for wideband quadrature signal generation with reduced sensitivity to component mismatch. In addition, polyphase networks represent a passive implementation of complex analog filters used for ima... View full abstract»

  • Autoregressive parameter estimation from noisy data

    Publication Year: 2000, Page(s):71 - 75

    A least-squares based method for noisy autoregressive signals has been developed recently, which needs to neither prefilter noisy data nor perform parameter extraction. In this brief, a more computationally efficient procedure for estimating the measurement noise variance is developed, and then an efficient implementation of the method is presented. It is shown that this better way of implementati... View full abstract»

  • Phase noise in a differential CMOS voltage-controlled oscillator for RF applications

    This paper presents theoretical and experimental results on phase noise of differential CMOS oscillators. A simple analytical expression is derived and verified by simulation which relates the phase noise including the device excess noise factor to circuit parameters. In agreement with the theoretical results, an experimental 1.9-GHz oscillator yielded phase noise as low as -100 dBc/Hz at 100-kHz ... View full abstract»

    In this paper, a new method for evaluating output frequency responses of nonlinear systems under multiple inputs, defined as a sum of sinusoids of different frequencies, is developed. The method circumvents difficulties associated with the existing “frequency-mix vector” based approaches and can easily be applied to investigate nonlinear behaviors of practical systems, including electr...

  • A “double-face” bit-serial architecture for the 1D discrete wavelet transform

    Publication Year: 2000, Page(s):65 - 71

    Proposes a novel discrete wavelet transform (DWT) architecture which is fully scalable, flexible, and modular. This architecture is bit serial, and therefore, has low hardware complexity and low power requirement. Nevertheless, because of its particular structure, it operates on-the-fly (i.e., it does not require wait cycles between consecutive input samples). Moreover, a very small hardware overh...

  • A multicarrier QAM modulator

    A multicarrier quadrature amplitude modulation (QAM) modulator has been developed and implemented with programmable logic devices. The multicarrier QAM modulator contains four CORDIC-based QAM modulators. A conventional QAM modulator needs two multipliers, one adder, and sine/cosine ROM's. The designed CORDIC-based QAM modulator has about the same logic complexity as the two multipliers and the ad... View full abstract»

  • Stochastic formulation of bandlimited signal interpolation

    We formulate the problem of bandlimited signal interpolation within a stochastic framework. Existing literature on this subject is fragmented and requires deep knowledge of probability, functional analysis, and estimation theory. In addition, previous developments have not clarified the relationship between the theories for the stochastic and deterministic cases. We find that by formulating interp... View full abstract»

    In this paper, we are concerned with the design of a finite-impulse response (FIR) filter, such that the H norm of the filtering error-transfer function is minimized subject to the constraint that the filter output with a given input to the signal system is contained or bounded in a prescribed envelope. The filter design problem is formulated as a standard optimization problem wi... View full abstract»
