  • Improved design techniques for low-voltage low-power switched-capacitor delta-sigma modulators

    Creator:
    Grilo, Jorge
    Abstract:
    This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of improving the performance and optimizing for low power dissipation. This is accomplished by identifying critical elements whose performance can lead to increased power dissipation,...

  • Design techniques for low-voltage analog-to-digital converter

    Creator:
    Chang, Dong-Young
    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low-voltage conditions. There are several well-known techniques to bypass the problem. These approaches include: (1)...

  • Ultra low voltage DRAM current sense amplifier with body bias techniques

    Creator:
    Gang, Yung-jin, 1957-
    Abstract:
    The major limiting factor of DRAM access time is the low transconductance of the MOSFET's which have only limited current drive capability. The bipolar junction transistor(BJT) has a collector current amplification factor, β, times base current and is limited mostly by the willingness to supply this base current. This collector...
