  • Digital implementation of a mismatch-shaping successive-approximation ADC

    Creator:
    Coe, Matthew T.
    Abstract:
    Utilizing a two-capacitor topology, the digital implementation of an audio-band successive-approximation analog-to-digital converter (ADC) is explored in the context of mismatch-shaping where the mismatch estimates are accurate to the first order. A second-order Δ∑ loop was found to be effective in system simulations given a 0.1% capacitor mismatch. Spectral analysis...

    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...

  • High-accuracy circuits for on-chip capacitor ratio testing and sensor readout

    Creator:
    Wang, Bo, 1970-
    Abstract:
    The precise measurement of a capacitance difference or ratio in a digital form is very important for capacitive sensors, for CMOS process characterization as well as for the realization of precise switched-capacitor data converters, amplifiers and other circuits utilizing ratioed capacitors. This thesis introduces design techniques for on-chip capacitor ratio...

  • Design of a 1.8-V 14-bit [delta] - [sigma] A/D converter with 8X oversampling and 4 MHz Nyquist output rate

    Creator:
    Jiang, Ruoxin
    Abstract:
    In this dissertation, a new Δ∑ A/D converter is presented that is ideally suited for communication applications. It is based on a single-loop single-stage structure, which can realize a high maximum out-of-band quantization noise gain while maintaining stable operation and thus achieve 14-bit resolution at 8 times oversampling. A fifth-order...

  • Theoretical influence of untransposed transmission line construction on system losses and voltage balance

    Creator:
    Chanakorn, Chavalit
    Abstract:
    The purpose of this thesis is to investigate the necessity of transposition in the construction of overhead transmission lines. Line currents, line voltages and line losses of both the transposed and untransposed lines were calculated and compared for two different voltage classes. The conventional method of symmetrical components was used...

  • Time domain simulation of multiconductor lossy transmission lines by the method of characteristics

    Creator:
    Orhanovic, Neven
    Abstract:
    A numerical technique to compute the time domain response of multiconductor lossy uniform and nonuniform lines terminated in general nonlinear elements is presented. The technique is based on the generalized method of characteristics. The method transforms the original system of transmission line equations into a system of ordinary differential equations....

  • Improved design techniques for low-voltage low-power switched-capacitor delta-sigma modulators

    Creator:
    Grilo, Jorge
    Abstract:
    This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of improving the performance and optimizing for low power dissipation. This is accomplished by identifying critical elements whose performance can lead to increased power dissipation,...
