  • An ultra low power frequency reference for timekeeping applications

    Creator:
    Oporta, Hector Ivan
    Abstract:
    An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A subthreshold voltage regulator provides a supply voltage for the oscillator with minimum current consumption. The oscillator and regulator...

  • Low power design techniques for analog-to-digital converters in submicron CMOS

    Creator:
    Musah, Tawfiq
    Abstract:
    Advances in process technologies have led to the development of low-power high speed digital signal processing blocks that occupy small areas. These advances are critical in the development of portable electronic devices with small feature size and long battery life. However, the design of analog and mixed-signal building blocks, especially...

  • Low-power high-resolution delta-sigma ADC design techniques

    Creator:
    Wang, Tao
    Abstract:
    This dissertation presents a low-power high-resolution delta-sigma ADC. Two new architectural design techniques are proposed to reduce the power dissipation of the ADC. Compared to the conventional active adder, the direct charge transfer (DCT) adder greatly saves power by keeping the feedback factor of the active adder unity. However, the...

  • 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...
