  • High speed buffers for op-amp characterization

    Creator:
    Rangan, Giri N. K.
    Abstract:
    The feasibility of developing test circuits to perform in-circuit testing of analog circuits is investigated in this thesis. A modular approach to analog testing has been adopted. Accordingly, the testing of an operational amplifier, which is a basic building block in analog circuits, is addressed. One convenient technique for measuring...

  • OP-AMP free SC biquad LPF and delta-sigma ADC

    Creator:
    Yoo, Kiseok
    Abstract:
    The objective of this work is to explore the feasibility of replacing conventional op-amps with inverters in switched-capacitor (SC) circuits. In order to verify the idea, a low-pass filter (LPF) and a second-order delta-sigma (∆Σ) analog-todigital converter (ADC) are designed in the 0.5-m CMOS technology. The low-pass filter structure is...

  • High-linearity switched-capacitor circuits in digital CMOS technologies

    Creator:
    Yoshizawa, Hirokazu
    Abstract:
    In this thesis, novel design techniques have been proposed for implementing high-linearity SC circuits in a standard digital CMOS process. They use nonlinear MOSFET capacitors instead of linear double-poly capacitors. To reduce their nonlinearities, a bias voltage is applied to keep MOSFET capacitors in their accumulation regions. For further reduction...

  • Low power high resolution data converter in digital CMOS technology

    Creator:
    Zheng, Zhiliang
    Abstract:
    The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...

  • Effect of prerigor pressurization on postmortem biochemical changes in beef muscle

    Creator:
    Elkhalifa, Elamin Abdalla
    Abstract:
    Prerigor pressurization of bovine semimembranosus muscle at 103.5 MNm⁻² (15,000 psi) for two min at 35°C significantly decreased (P<0.01) muscle pH, and significantly (P<0.01) increased the rate of glycogen degradation during the first 4 hr postmortem. Glycogen levels of pressurized muscle were significantly (P<0.01) lower than those of the control...

  • Predicting Aerodynamic Loads on Highly Flexible Membrane Wings

    Creator:
    Carpenter, Trenton James
    Abstract:
    Through passive adaptation to incidental flow, flexible aerodynamic surfaces exploit effects of increased lift, delayed stall and disturbance rejection. Wings of birds, bats, and insects exhibit these passive effects, and at the same time through the use of structural state feedback sensed from the loads on the wing, active control...

  • Institutionalizing Science in Oregon : The Role of the Oregon State Academy of Sciences, 1905-1914

    Creator:
    Read, Richard Thomas
    Abstract:
    In February 1905 the Oregon State Academy of Sciences formed in Portland to promote scientific research and diffusion of scientific knowledge in Oregon. The founders also planned to assist in the discovery and development of the state's natural resources. The Academy was the first scientific society in Oregon with professional...

  • Random dopants and low-frequency noise reduction in deep-submicron MOSFET technology

    Creator:
    Miller, Drake A.
    Abstract:
    The future of mixed-signal, memory, and microprocessor technologies are dependent on ever increasing analog and digital integration, higher cell densities, and demand for more processing power. As a result MOSFET device dimensions continue to shrink to meet these demands. A side effect of device scaling is increased variability at each...

  • The effect of prerigor electrical stimulation pH decline, protein solubility and water holding capacity in beef muscles

    Creator:
    Elkhalifa, Elamin Abdalla
    Abstract:
    This study was designed to investigate the rate of pH decline, changes in protein solubility and in the water-holding capacity (WHC) of beef muscles subjected to pre-rigor electrical stimulation. Samples for the experiment were obtained from animals slaughtered at the Meat Science Laboratory, Oregon State University. Nine good quality steers...

  • Teacher argumentation in the secondary science classroom : images of two modes of scientific inquiry

    Creator:
    Gray, Ron E.
    Abstract:
    The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and...
