  • Via-only microwave/millimeter wave bandpass filters for LTCC applications

    Creator:
    Bhargava, Gaurav
    Abstract:
    With an increasing number of wireless applications at microwave frequencies, the frequency spectrum is becoming quite crowded. Due to this congestion, the current state of technology is leading towards upper microwave and millimeter wave spectra as they also offer other distinct advantages such as larger bandwidth and smaller component footprint....

  • Comparison and impact of substrate noise due to clocked and clockless circuitry

    Creator:
    Le, Jim K.
    Abstract:
    Delay insensitive asynchronous circuitry provides significant advantages with respect to substrate noise due to localized switching. The differences between the substrate noise from NULL Convention Logic (NCL) and traditional Clocked Boolean Logic (CBL) are described and analyzed based on measured results. A test chip fabricated in the TSMC 0.25 um...

  • Adaptive, wideband analog-to-digital conversion for convergent communication systems

    Creator:
    Batten, Robert D., 1973-
    Abstract:
    The exponential rate of advances in modern communication devices in the last several years have brought us higher levels of functionality and performance as well as reductions in physical size and power consumption. To continue this rate of advancement, next generation systems require wider bandwidth and higher resolution ADCs. Additionally,...

  • Growth and characterization of zinc ferrite thin films for high frequency applications

    Creator:
    Hu, Jiqing
    Abstract:
    Ferrites have been used for various high frequency applications as bulk materials. These applications, however, are limited to large dimension devices. In this thesis, thin film ferrites were deposited from a low temperature solution-based deposition process that is suitable for micro-scale high frequency applications. The low temperature nature of this...

  • Modified VLSI designs for error correction codes

    Creator:
    Chen, Lupin
    Abstract:
    Nowadays, error correction codes have become an integral part in almost all the modern digital communication and storage systems. With the continuously increasing demands for higher speed and lower power communication systems, efficient VLSI implementations of those error correction codes have great importance for practical applications. In this thesis, several...

  • High efficiency delta-sigma modulation data converters

    Creator:
    Lee, Kyehyung
    Abstract:
    Enabled by continued device scaling in CMOS technology, more and more functions that were previously realized in separate chips are getting integrated on a single chip nowadays. Integration on silicon has opened the door to new portable wireless applications, and initiated a widespread use of these devices in our common...

  • Novel power conditioning circuits for piezoelectric micro power generators

    Creator:
    Han, Jifeng
    Abstract:
    Advanced low power devices promote the development of micro power generators (MPGs) to replace the batteries to power them. Due to the trend in decreasing integrated circuit (IC) supply voltages, power supply designers are facing more and more serious challenges. The objective of this research is to design a power...

  • A fully digital technique for the estimation and correction of the DAC error in multi-bit delta sigma ADCs

    Creator:
    Wang, Xuesheng
    Abstract:
    This thesis proposes a novel fully digital technique for the estimation and correction of the DAC error in multi-bit delta sigma ADCs. The structure of the DAC error is indicated through a simple model for unit-element based DACs. The impact of the DAC error on the performance of ADC is...

  • Architecture design of multiplexed incremental analog-to-digital converters

    Creator:
    Zhang, Zhiqing
    Abstract:
    Analog-to-Digital Data Converters (ADCs) used in instrumentation and measurements often require high absolute accuracy, including excellent linearity and negligible dc offset. Incremental data converters (IDCs) provide a solution for such measurement applications. Since IDCs are essentially delta-sigma converters with reset operation before each conversion, they retain most of the advantages...
