  • Transparent electronics : thin-film transistors and integrated circuits

    Creator:
    Presley, Rick E.
    Abstract:
    This thesis focuses on two aspects of transparent electronics, SnO₂ transparent thin-film transistors (TTFTs) and transparent circuits. Both depletion- and enhancement-mode SnO₂ TTFTs are realized. The maximum effective mobility for the depletion- and enhancement-mode devices are 2 cm²V⁻¹s⁻¹ and 0.8 cm²V⁻¹s⁻¹, respectively. A variety of techniques to decrease the carrier...

  • Equalizer design for MDFE channels using nonlinear optimization

    Creator:
    Onu, Dan
    Abstract:
    Decision feedback equalization (DFE) is a sampled-data technique used for data recovery in digital communications channels. Multi-level decision feedback equalization (MDFE) has been developed for channels using the 2/3(1,7) RLL code. The optimum detector for a digital communication channel affected by ISI and noise consists of a matched filter, followed...

  • Designing a high level microprogramming language

    Creator:
    Malik, Kamran
    Abstract:
    The purpose of this research is to design a high level language (HLL) suitable for microprogramming. A top down design technique has been adopted which makes the language design process simple and accurate. The primitive operations of a high level language for producing emulators is shown to include special purpose...

  • 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...

  • Novel switched-capacitor circuits for delta-sigma modulators

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Oversampled delta-sigma modulation is one of the widely used A/D conversion techniques for narrow bandwidth signals. In this study several new lowpass and bandpass delta-sigma modulator architectures as well as novel pseudo-N-path integrators that can be used in implementing these architectures are proposed. By using multiplexing techniques the new lowpass...

  • Atomic Layer Processing for Next-Generation Microelectronic Materials

    Creator:
    Holden, Konner E. K.
    Abstract:
    Atomic layer deposition (ALD) is an enabling technique for many new micro- and nanoscale technologies. The self-limiting surface chemical reactions by which ALD fundamentally operates give rise to uniquely high precision (atomic) control over deposited film thickness, uniformity over large areas, and conformality over complex and extreme topographies. One such...

    Creator:
    Kang, Yong Joong
    Abstract:
    FISHNET (Facilities Integrated in a Shared Habitat) is a communication subnet architecture utilizing a hybrid application of point-topoint and broadcast communications to achieve a high degree of network performance. This objective is achieved through utilizing a dual bus structure: a data bus and a control bus. The data bus consists...

  • Atomic solid state energy scale applied to novel thin-film solar absorbers

    Creator:
    Pelatt, Brian D.
    Abstract:
    The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...

    Chiang, Tsung-Han
    Abstract:
    The objective of the work reported herein is to explore the impact of decreasing channel thickness on radio-frequency (RF) sputtered amorphous indium-gallium-zinc oxide (a-IGZO) thin-film transistors (TFTs) electrical performance through the evaluation of drain current versus gate voltage (I[subscript D] − V[subscript G]) transfer curves. For a fixed set of...

  • Switch-capacitor Power Amplifier with Enhanced Power Back-off Efficiency and Linearity

    Creator:
    Qiao, Bo
    Abstract:
    Nowadays, wireless communication systems use high-order quadrature amplitude modulation (QAM) together with orthogonal frequency-division multiplexing (OFDM) to increase the link capacity and robustness. These signals always have large peak-to-average power ratio (PAPR) and require power amplifiers (PAs) achieve both high efficiency and linearity simultaneously. For the efficiency, the complementary metal...
