  • Amorphous oxide semiconductor thin-film transistor ring oscillators and material assessment

    Creator:
    Sundholm, Eric Steven
    Abstract:
    Amorphous oxide semiconductor (AOS) thin-film transistors (TFTs) constitute the central theme of this thesis. Within this theme, three primary areas of focus are pursued. The first focus is the realization of a transparent three-stage ring oscillator with buffered output and an output frequency in the megahertz range. This leads to...

  • Electrical recommendations and formulas for metal fill in radio-frequency integrated circuits

    Creator:
    Gaskill, Steven
    Abstract:
    With increasing transistor operating frequencies, interconnects and passive devices are becoming performance limiters in integrated circuit (IC) designs. To combat this, the interconnect layers above the active silicon are trending toward low-κ dielectrics and Cu metallization. The use of these new materials has popularized chemical mechanical polishing (CMP) to planarize...

  • Enabling metal-fill-aware design of integrated circuits

    Creator:
    Shilimkar, Vikas S.
    Abstract:
    In advanced integrated circuit (IC) processes, the metal fill inserted to meet foundry imposed density requirements degrades the performance of interconnects and passive components which ultimately affects the overall circuit performance. Accounting for this degradation through electromagnetic and equivalent circuit modeling is becoming a critical aspect of IC design. However,...

  • Non-Stoichiometry in Bismuth Perovskite Solid Solutions

    Creator:
    Prasertpalichat, Sasiporn
    Abstract:
    The role of A-site non-stoichiometry was investigated in lead-free piezoelectric ceramics based on compositions in the 1-x(Bi₀.₅Na₀.₅TiO₃)-xBaTiO₃ system near the morphotropic phase boundary where x = 0.055, 0.06 and 0.07. The samples were prepared by a conventional solid state mixed oxide route with the A- site stoichiometry modified to incorporate...

  • Wideband discrete-time delta-sigma analog-to-digital converters with shifted loop delays

    Creator:
    Meng, Xin
    Abstract:
    Low-distortion architecture is widely used in wideband discrete-time switched-capacitor delta-sigma ADC design. However, it suffers from the power-hungry active adder and critical timing for quantization and dynamic element matching (DEM). To solve this problem, this dissertation presents a delta-sigma modulator architecture with shifted loop delays. In this project, shifted loop...
