  • Power Efficient Architectures for Medium-high Resolution Analog-to-Digital Converters

    Creator:
    Sadollahi, Mahmoud
    Abstract:
    Analog-to-digital converters are essential components to the portable devices that we are using today. Wireless sensors, body implanted devices, communication devices and so forth require low power ADCs. Therefore achieving higher resolution and bandwidth with lower power consumption is targeted in ADCs design. In this work power efficient ADCs for...

  • Analysis and design on low-power multi-Gb/s serial links

    Creator:
    Hu, Kangmin
    Abstract:
    High speed serial links are critical components for addressing the growing demand for I/O bandwidth in next-generation computing applications, such as many-core systems, backplane and optical data communications. Due to continued process scaling and circuit innovations, today's CMOS serial link transceivers can achieve tens of Gb/s per pin. However, most...

  • Low-complexity high-speed VLSI design of low-density parity-check decoders

    Creator:
    Cui, Zhiqiang
    Abstract:
    Low-Density Parity-check (LDPC) codes have attracted considerable attention due to their capacity approaching performance over AWGN channel and highly parallelizable decoding schemes. They have been considered in a variety of industry standards for the next generation communication systems. In general, LDPC codes achieve outstanding performance with large codeword lengths (e.g.,...

  • A channelized digital receiver design for UWB sytems in a multipath indoor environment

    Creator:
    Chang, Yuhao
    Abstract:
    This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...

  • Linearity enhancement techniques for data converters

    Creator:
    Cao, Jinzhou
    Abstract:
    Data converters are essential interface circuits between the analog world that people live in and the digital processors that people live with. Linearity, which often is a tradeoff against other performance criteria, is one of the major performance demands from applications for both analog-to-digital converts (ADC) and digital-to-analog converters (DAC)....

  • Opportunistic bandwidth sharing through reinforcement learning

    Creator:
    Venkatraman, Pavithra
    Abstract:
    The enormous success of wireless technology has recently led to an explosive demand for, and hence a shortage of, bandwidth resources. This expected shortage problem is reported to be primarily due to the inefficient, static nature of current spectrum allocation methods. As an initial step towards solving this shortage problem,...
