  • A Microwave Signal Correlator Based on Parametric Pumping of Spin Waves

    Creator:
    Hansen, Mikkel N.
    Abstract:
    This work demonstrates correlation of microwave signals encoded with 16-bit codes using the parametric interaction of spin waves. Signal processing correlators are devices that compare two signals, such as a reference code and a received code, where the output indicates the similarity between the signals. Correlators are used in communication...

  • A dual-path 2-0 MASH ADC with dual digital error correction

    Creator:
    Zhang, Zhenyong
    Abstract:
    This dissertation presents a dual-path 2-0 MASH (Multi-stAge-noise -SHaping) ADC with two verified digital corrections of DAC mismatch error and quantization noise leakage. By using these two techniques, the requirements for the analog circuits are greatly relaxed. The dual-path structure generates two outputs, one only composed of conversion errors, the...

  • Design techniques for low-power multi-GS/s analog-to-digital converters

    Creator:
    Jiang, Tao
    Abstract:
    Ultra-high-speed (>10GS/s), medium-resolution (5~6bit), low-power (<50mW) analog-to-digital converter can find it application in the areas of digital oscilloscopes and next-generation serial link receivers. There are several challenges to enable a successful design, however. First, the time-interleaved architecture is required in order to achieve over 10GS/s sampling rate, with the trade-off...

  • Energy-efficient, short-range ultra-wideband radio transceivers

    Creator:
    Hu, Changhui
    Abstract:
    Short-range wireless communications continually attract interest from both industry and academia, and it is changing our life in every aspect in the last decade. The design of wireless transceivers is the bottleneck for variety applications, due to RF modeling inaccuracy, stringent FCC regulations over the transmitted power spectrum, interference, multi-path...

  • 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...

  • Efficient VLSI architectures for MIMO and cryptography systems

    Creator:
    Li, Qingwei
    Abstract:
    Multiple-input multiple-output (MIMO) communication systems have recently been considered as one of the most significant technology breakthroughs for modern wireless communications, due to the higher spectral efficiency and improved link reliability. The sphere decoding algorithm (SDA) has been widely used for maximum likelihood (ML) detection in MIMO systems. It is...

  • Energy efficient communication across on-chip wires in digital CMOS

    Creator:
    Postman, Jacob
    Abstract:
    For the past half century, CMOS process scaling has followed Moore's law, approximately doubling transistor density every 18 months. While locally routed wires have generally scaled with transistor size, longer wires have scaled at a slower rate and in some cases have grown larger as chip size and complexity have...

  • The Architecture of a Reusable Built-In Self-Test for Link Training, IO and Memory Defect Detection and Auto Repair on 14nm Intel SOC

    Creator:
    Querbach, Bruce
    Abstract:
    The complexity of designing and testing today's system on chip (SOC) is increasing due to greater integrated circuit (IC) density and higher IO and memory frequencies. SOCs for the mobile phone and tablet market have the unique challenge of short product development windows, at times less than six months, and...
