    In order to analyze complex oscillations with a large deviation for a nonlinear nonautonomous power-transmission system, heteroclinic and subharmonic bifurcations are discussed by technically computing Melnikov functions with the residue of a complex function and elliptic integrals, which gives a condition of parameters for chaotic oscillation and one for periodic oscillation. We describe the thre... View full abstract»

    With increasing demand for higher data rate, modern communication systems have grown more complex. Equalization has become more and more important as it is effective in mitigating the multipath fading often occurred in high-data-rate communication systems. However, the implementation complexity of adaptive equalizers is usually too high for mobile communication applications. In this paper, a novel... View full abstract»

  • Self-calibration of input-match in RF front-end circuitry

    The input match of RF front-end circuitry can degrade significantly due to process faults and parasitic package inductances at its input pad. The proposed technique ascertains the input match frequency of the circuit by using a built-in self-test (BiST) structure, determines the frequency interval by which it needs to be shifted to restore it to the desired value, and then feeds back a digital wor...

    The problem of survival memory management of a Viterbi decoder (VD) was solved by introducing a novel pointer implementation for the register exchange method, where a pointer is assigned to each row of memory in the survivor memory unit (SMU). The content of the pointer which points to one row of memory is altered to point to another row of memory, instead of copying the contents of the first row ... View full abstract»

    A low-voltage fully differential, voltage-controlled transconductor is described. The proposed transconductor achieves a wide input/control voltage range, with a highly linear transconductance factor and truly fully differential output currents. The transconductor is used to implement a Gm-C adaptive forward equalizer (FE) for a 125 Mbps wire line transceiver using digital core transist... View full abstract»

  • A theory for deriving exactly solvable nonuniform transmission lines systematically

    A general idea is given for a systematic and recursive technique to derive exactly solvable LC lines one after another. It consists of three simple operations, i.e., the Liouville transformation (LT) applied to the Telegrapher's equation, its inverse, and LC exchange (LCX). The differential equation obtained as a result of the LT is unique for a specific original line and is called a Liouville nor... View full abstract»

    As the minimum feature size of VLSI technologies scales down, more of the signal processing tasks are performed in the digital domain. This results in increased speed, resolution, and dynamic range requirements for the analog-to-digital converter (ADC). High-speed and high-accuracy designs can be achieved by using oversampling ADC structures, which demand amplifiers with a high gain and a high uni... View full abstract»

  • Rigorous Q-factor formulation for one- and two-port passive linear networks from an oscillator noise spectrum viewpoint

    Publication Year: 2005, Page(s):846 - 850

    This brief characterizes one- and two-port passive networks from the viewpoint of oscillator design. A linear circuit theory derives the spectral spread due to RF noise from active devices. The formulation finds a frequency derivative function of logarithmic immittance that plays the key role of dominating the spectrum behavior. This leads to an explicit definition of the Q factor by referring to ... View full abstract»

    Protein sequences with unknown functionality are often compared to a set of known sequences to detect functional similarities. Efficient dynamic-programming algorithms exist for solving this problem, however current solutions still require significant scan times. These scan time requirements are likely to become even more severe due to the rapid growth in the size of these databases. In this paper... View full abstract»

    In this paper, an improved ac pixel electrode circuit for active-matrix organic light-emitting display (AMOLED) has been proposed by adding a thin-film transistor. This circuit can provide an ac driving mode for AMOLED and makes the OLED in a reversed-biased voltage during the reverse cycle. And a circuit design for understanding ac driving mode was presented. The circuit simulation results indica... View full abstract»

    Although a number of single current feedback op-amps (CFOA)-based single-resistance-controlled oscillators (SRCO) have appeared in earlier literature, only six of them are canonic (i.e., requiring only two capacitors and only three resistors). The object of this brief is to add to this list two new canonic single-CFOA-based SRCO configurations. An evaluation of these two new circuits has been carr... View full abstract»

    This brief deals with the recursive parameter identification of Hammerstein type nonlinear dynamic systems with time-varying piecewise-linear characteristics. A special form of the Hammerstein model, which is linear in parameters, is incorporated into the recursive least squares identification scheme supplemented with the estimation of model internal variables. This enables online estimation of th... View full abstract»

    In this paper, a simple nonlinear recursive delayed feedback controller is designed for stabilizing periodic solutions of a nonlinear system. The proposed controller is constructively designed and does not inherit the odd number limitation. The stability of the periodic solution of the closed-loop system is proved rigorously. Applying the control method to chaotic systems, one can effectively cont... View full abstract»

    The conventional common-gate low-noise amplifier (CGLNA) exhibits a relatively high noise figure (NF) at low operating frequencies relative to the MOSFET fT, which has limited its adoption notwithstanding its superior linearity, input matching, and stability compared to the inductively degenerated common-source LNA (CSLNA). A capacitor cross-coupled gm-boosting scheme is desc... View full abstract»
