  • A multi-bit hybrid DSM over full-scale range without feedback DEM

    Creator:
    Kwon, Sunwoo, 1974-
    Abstract:
    Evolution of the mobile communication standards and proliferation of hand-held devices mandate stringent Analog-to-Digital Converter (ADC) specifications. Among various ADCs, a ∆Σ ADC is best known as a power-efficient ADC when more than 12b is required. However, a conventional discrete-time (DT) ∆Σ Modulator (∆ΣM) is inadequate for low-power wideband applications...

  • An ultra low voltage micropower GPS receiver RF front-end for wildlife tracking

    Creator:
    Heiberg, Adam C.
    Abstract:
    A fully integrated CMOS GPS receiver RF front end optimized for low power operation is presented. The system operates with a supply voltage down to 250 mV. A prototype has been fabricated in a 0.13μm CMOS process and includes a low voltage LNA, quadrature oscillators, and quadrature mixers. It exhibits...

  • Throughput optimization for single-hop wireless networks using network coding

    Creator:
    Tran, Tuan Tho
    Abstract:
    Recent advances in wireless technologies have helped the proliferation of wireless devices, ranging from hand-held devices such as cellular phones to more powerful mobile computing platforms as such laptops [1]. Along with that, the end users’ applications running on these devices, ranging from text message to multimedia applications such as...

  • Dual referencing guidelines to minimize power delivery noise coupling

    Creator:
    Mark, Shannon
    Abstract:
    Dual referencing has been garnering a lot of attention in the power integrity community, specifically in the voltage mode driver application because it shows a lower overall power delivery noise (PDN) compared to other signal referencing types. Additionally, the increasing push to drive down package and board manufacturing costs is...

  • 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)....

  • Single-level dynamic register caching architecture for high-performance superscalar processors

    Creator:
    Liebert, John A.
    Abstract:
    The amount of instruction level parallelism (ILP) that can be exploited depends greatly on the size of the instruction window and the number of in-flight instructions the processor can support. However, this requires a register file with a large set of physical registers for renaming and multiple ports to provide...

  • Resource allocation methods for quality-of-service provisioning in heterogeneous wireless networks

    Creator:
    Chakchouk, Nessrine
    Abstract:
    The increased use of mobile wireless devices that we have recently been witnessing, such as smartphones, tablets, e-readers, and WiFi enabled devices in general, is driving an unprecedented increase in the amount of data traffic. This fast market adoption of the wireless technology along with the tremendous success of multimedia...

  • Low-power dynamic CMOS circuits in high-performance memory arrays

    Creator:
    Patwary, Md. Ataur R.
    Abstract:
    Dynamic CMOS circuits are commonly used in high-performance memory arrays to implement wide-NOR logic functions for their read and search operations. This is because dynamic circuits have significantly higher speed and lower area compared to static circuits for performing similar operations. Register File (RF) arrays are located at the top...

    Creator:
    Liew, Ji Seok
    Abstract:
    Achieving sharpened (enhanced detail) features of a multi-dimensional data source using the linear prediction (LP) bandwidth extrapolation (BWE) technique in the transform domain is the main objective of this research. The evolution of sensor technology has provided acquisition scenarios in which the data format is inherently multi-dimensional, including hyperspectral imaging...
