  • Low-voltage data converters

    Creator:
    Meng, Qingdong
    Abstract:
    With the growing demand for portable/consumer electronics, such as digital audio/video (AV), the downscaling of device dimensions, which enables the integration of an increasing number of transistors in a single chip, is mandatory. This trend also continuously pushes the power supply voltage down to reduce the power consumption and improve...

  • A multi-bit delta sigma audio digital-to-analog converter

    Creator:
    Wang, Ruopeng
    Abstract:
    Digital-to-analog converters (DACs) with wide dynamic range and high linearity are required for high-end audio applications. A multi-bit delta sigma audio DAC, using a novel gain-correction technique, is described in this thesis. For widely varying on-chip RC time constant, the DAC gain can be accurately controlled by the correction circuitry....

  • Improved design techniques for analog and mixed circuits

    Creator:
    Nishida, Yoshio
    Abstract:
    Although the digital revolution can realize many of past analog components in the digital forms, our world is surrounded with analog signals such as voice, temperature, etc. The bridge between these two worlds is one of key performance limitations among overall systems and it includes analog filters and data converters....

  • Noise optimization for low-voltage CMOS audio preamplifier systems

    Creator:
    Brown, Matthew Eugene
    Abstract:
    There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...

  • A wideband low-power continuous-time delta-sigma modulator for next generation wireless applications

    Creator:
    Chen, Xuefeng
    Abstract:
    Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are widely used in wireless transceivers. Recently, continuous-time (CT) ΔΣ ADCs gain growing interest in wireless applications for their lower power consumption and wider input bandwidth as compared with the discrete-time (DT) counterparts. In this thesis, a wideband low-power CT ΔΣ modulator for next generation...

  • Noise coupling techniques in multi-cell delta-sigma modulators

    Creator:
    Bonu, Madhulatha
    Abstract:
    High performance multi-cell delta-sigma modulators are a preferred choice in applications which require programmability. Multi-cell delta-sigma modulators with M unit cells provide 10log10(M) SQNR improvement for the same thermal noise and bias power due to the uncorrelated quantization noises of the M unit ADCs. This concept is used in this...
