  • 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...

  • 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...

  • Millimeter-Wave Wideband Low-Noise Amplifiers in 22FFL Technology

    Creator:
    Gupta, Soumya
    Abstract:
    The deployment of advanced technology standards for 5G and beyond in cellular networks has resulted in interest in integrated circuits (ICs) operating at frequencies above 10GHz. This has sparked research on wideband circuits in commercial low-cost silicon technologies, operating at high RF and mm-wave frequencies. Given the wide range of...

  • 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...

  • Low-Power 12-bit Quasi-Passive Segmented DAC Implemented in 130nm CMOS Technology

    Creator:
    Pierce, Alexander G.
    Abstract:
    This thesis work proposes a low-power 12-bit digital-to-analog converter (DAC) designed in a 130nm process. The DAC to be presented is of a segmented design where the architecture is split into pipelined and thermometer coded segments. This allows for high linearity and low distortion while maintaining high speed and low...

  • 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...

  • Substrate noise coupling analysis in 0.18um silicon germanium (SiGe) and silicon on insulator (SOI) processes

    Creator:
    Pham, Hui En
    Abstract:
    Analysis of substrate noise coupling has been performed for a 0.18¹m lightly doped silicon germanium BiCMOS process. Techniques to minimize noise coupling in the chip and board design are presented, as well as methods for accurate modeling for substrate noise coupling simulations. Measurements from a test chip were taken to...

  • Soft Robotics in Radiation Environments : A Prospective Study of an Emerging Automated Technology for Existing Nuclear Applications

    Creator:
    Oshiro, Tyler T.
    Abstract:
    Traditional robots have a long history in nuclear-related work because their integration decreases risk to humans in dangerous environments. Soft robotics is one promising new branch of traditional robotics with proposed applications in industry, medicine, and society. Collaborators from the Robotics mLab at Oregon State University (OSU) are currently working...
