  • High efficiency delta-sigma modulation data converters

    Creator:
    Lee, Kyehyung
    Abstract:
    Enabled by continued device scaling in CMOS technology, more and more functions that were previously realized in separate chips are getting integrated on a single chip nowadays. Integration on silicon has opened the door to new portable wireless applications, and initiated a widespread use of these devices in our common...

  • Generalized radix design techniques for low-power, low voltage pipelined and cyclic analog-digital converters

    Creator:
    Sharma, Vivek
    Abstract:
    This thesis proposes a novel technique for the design of pipelined and cyclic ADCs utilizing generalized radix gain stages. Several models have been proposed for the optimization of high performance pipelined ADCs by various researchers. This work builds upon them, using a simple but accurate model to estimate the optimal...

  • 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...

  • 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...

  • 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...

  • High-performance delta-sigma analog-to-digital converters

    Creator:
    da Silva, Jose Barreiro
    Abstract:
    Multi-stage delta-sigma (ΔΣ) architectures, commonly known as MASH, are the preferred choice for analog-to-digital converters (ADCs) used in broadband communication applications, where high-resolution (above 14 bits) and high-bandwidth (several MHz) performances are required. Current state-of-the-art designs are capable of as much as 5-MS/s output data rates with 90-dB SNR. However,...

  • 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)....

  • 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...
