  • Digitally-programmable switched-current filters

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Digitally-programmable filters have been an ongoing research topic for a number of years. The first such filters were FIR transversal filters using Charge-Coupled Devices (CCD's) and IIR recursive filters using switched-capacitor (SC) techniques. Although both techniques achieve excellent results, they require non-standard and/or additional IC fabrication steps. Low substrate doping...

  • A universal CMOS current-mode operational amplifier

    Creator:
    Botelho, Cindy
    Abstract:
    It has become customary in electrical engineering to think of signal processing in terms of voltage variables to the exclusion of current variables. This tendency has resulted in voltage signal processing circuits such as voltage-controlled voltage sources (VCVS) and voltage-mode operational amplifiers. However, the VCVS operational amplifier has several limitations...

  • Hypervelocity spectroscopy from impacts in polymeric materials

    Creator:
    Buettner, Douglas J.
    Abstract:
    Stacked sheets of polyethylene terephthalate andpolystyrene provide a means for recovering projectiles travelling at hypervelocities. The transparency of these multiple diaphragms is utilized so that light generated from hypervelocity impacts can be studied. A method for gathering visible as well as ultraviolet light from less transparent polymer foams has been...

  • Fully-differential current-mode CMOS circuits and applications

    Creator:
    Zele, Rajesh H.
    Abstract:
    With increasing interest in current-mode analogue processing due to its high performance properties such as speed, bandwidth and accuracy compared to voltage-mode processing, new current-mode alternatives to various conventional circuit designs are appearing. In this report, a novel circuit design to construct a fully-differential current-mode operational amplifier ( OP-AMP )...

  • Current-feedthrough cancellation technique for current-mode T/H circuits

    Creator:
    Young, David Y. W.
    Abstract:
    In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

  • High accuracy CMOS switched-current ladder filters

    Creator:
    Hoei, Jung-sheng
    Abstract:
    Clock-feedthrough effects, channel-length modulation and device mismatch are the main causes of the inaccuracy of Switched-Current (SI) circuits. In this paper, these non-ideal effects are analyzed. A high-performance current mirror, namely regulated cascode current mirror, which eliminates drain voltage variation problem is introduced. By using this current mirror as a...

  • The effect of void distribution on the Hugoniot state of porous media

    Creator:
    Creel, Emory Myron Willett
    Abstract:
    Shocked porous granular material experiences pressure dependent compaction. D. John Pastine introduced a model in which the degree of compaction is dependent on the pressure induced by the shock wave, the shear strength of the material, and the distribution of void sizes. In the past, the model could only be...

  • Design of high-speed low-power analog CMOS decision feedback equalizers

    Creator:
    Su, Wenjun
    Abstract:
    Decision feedback equalizer (DFE) is an effective method to remove inter-symbol interference (ISI) from a disk-drive read channel. Analog IC implementations of DFE potentially offers higher speed, smaller die area, and lower power consumption when compared to their digital counterparts. Most of the available DFE equalizers were realized by using...
