  • Characterization and electrical circuit modeling of interconnections and packages using time domain network analysis

    Creator:
    Hayden, Leonard
    Abstract:
    The improved accuracy of Time Domain Reflection and Transmission (TDR/T) measurements made possible by the calibration process known as Time Domain Network Analysis (TDNA) is applied to the problem of characterization and modeling of electronic interconnect and packaging structures. TDNA uses measurements of known and partially known calibration standards to...

  • Low-power high-performance 32-bit 0.5[u]m CMOS adder

    Creator:
    Shah, Parag Shantu
    Abstract:
    Currently, the two most critical factors of microprocessor design are performance and power. The optimum balance of these two factors is reflected in the speed-power product(SPP). 32-bit CMOS adders are used as representative circuits to investigate a method of reducing the SPP. The purpose of this thesis is to show...

  • A pipelined baseband digital predistortion architecture for RF amplifier linearization

    Creator:
    Xu, Xiangqing
    Abstract:
    This thesis describes the design of a baseband digital predistortion architecture for radio frequency (RF) amplifier linearization. Existing amplifier linearization techniques are first examined. The nonlinearity of an amplifier can be characterized as amplitude-to-amplitude distortion and amplitude-to-phase distortion. The distortion can be corrected by providing a predistorted driver signal (both...

  • Capacitance-voltage analysis, SPICE modeling, and aging studies of AC thin-film electroluminescent devices

    Creator:
    Davidson, James D. (James Douglas), 1960-
    Abstract:
    Alternating-current thin-film electroluminescent (ACTFEL) devices are metal-insulator-semiconductorinsulator- metal (MISIM) structures which emit light under high field, pulsed excitation. One aspect of ACTFEL operation that is not well understood is the aging of such devices with operating time. One of the primary goals of this thesis is to characterize the kinetics...

  • Digitally-programmable switched-current filters

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Digitally-programmable filters have been an ongoing research topic for a number of years. The first such filters were FIR transversal filters using Charge-Coupled Devices (CCD's) and IIR recursive filters using switched-capacitor (SC) techniques. Although both techniques achieve excellent results, they require non-standard and/or additional IC fabrication steps. Low substrate doping...

  • High accuracy CMOS switched-current ladder filters

    Creator:
    Hoei, Jung-sheng
    Abstract:
    Clock-feedthrough effects, channel-length modulation and device mismatch are the main causes of the inaccuracy of Switched-Current (SI) circuits. In this paper, these non-ideal effects are analyzed. A high-performance current mirror, namely regulated cascode current mirror, which eliminates drain voltage variation problem is introduced. By using this current mirror as a...

  • VLSI implementation of adaptive BIT/serial IIR filters

    Creator:
    Badyal, Rajeev
    Abstract:
    A new structure for the implementation of bit/serial adaptive IIR filter is presented. The bit level system consists of gated full adders for the arithmetic unit and data latches for the data path. This approach allows recursive operation of the IIR filter to be implemented without any global interconnections, minimal...

  • Low noise FSCL digital circuits for decimation filter

    Creator:
    Wong, Man Wa
    Abstract:
    A new circuit technique called Folded Source Coupled Logic (FSCL) has been developed to implement the digital section of mixed-signal IC applications. This FSCL circuit technique offers the advantage of low overlap current spikes during the switching transitions of conventional CMOS gates. This overlap current spike has become one of...

  • A programmable BiCMOS transconductance-capacitor filter for high frequencies

    Creator:
    Beck, Jeffery S.
    Abstract:
    With advancements in CMOS technology, high speed analog circuits that were traditionally implemented with discrete circuit components can now be made monolithically. Antialiasing filters for video signals as well as signal conditioning filters in high speed communication channels are examples of applications where high frequency integrated circuits are now feasible....
