  • 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...

  • 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 )...

  • Distributed architecture and fast parallel algorithms in real-time robot control

    Creator:
    Binder, Eli Eliyahu
    Abstract:
    Control algorithms for accurate and fast moving robots require the use of the complete dynamic model of the robot. The complete dynamic model takes into account the nonlinearity and coupling terms of the whole structure. The time of computing the dynamic equations determines whether they are usable in practical applications....

  • Voltage analysis of PWM inverter fed induction motors

    Creator:
    Al-Ghubari, Fahad H.
    Abstract:
    Adjustable Speed Drive (ASD) systems are widely used in industry to effectively improve process efficiency and control. Typically, an ASD system consists of a motor with its speed controlled by a power electronics converter via varying the amplitude and frequency of the input voltage. However, several abnormal insulation failures of...

  • Analysis and modeling of electrically long MESFETS and coupled schottky lines

    Creator:
    Mohammed, Ahmed Sarhan
    Abstract:
    The properties of linear active coupled lines consisting of electrically long GaAs MESFET structures are investigated for possible applications as traveling-wave broad-band amplifiers. In addition, the nonlinear coupled Schottky lines are studied for applications as voltage tunable circuit elements. The analysis of the general active asymmetric coupled transmission lines in...

  • MOSFET-only predictive track and hold circuit

    Creator:
    Qiu, Xiangping
    Abstract:
    High-accuracy and high-speed CMOS track-and-hold (T/H) or sample-and-hold (S/H) circuits are an important part of the analog-to-digital interface. The switched-capacitor (SC) circuits usually contain one or more op-amps whose dc offset, finite gain, finite bandwidth have a big impact on the accuracy of the track-and-hold circuit. Basic correlated double sampling...

  • A parametric analysis of the capabilities of undersea acoustic imaging

    Creator:
    Calligan, C. C.
    Abstract:
    The feasibility of utilizing acoustic imaging techniques for improving the undersea viewing capability of small submersibles is investigated. The limiting values of major parameters in acoustic imaging systems are established and graphs which illustrate the parametric relationships are presented. A series of sample calculations illustrate how the graphs can be...

  • 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...
