  • Data driven optimization in SAR ADC

    Creator:
    Leung, Jerry
    Abstract:
    Recent publications show that successive approximation register (SAR) analog to digital converters (ADC) are capable of achieving high efficiency over other ADC topologies. Furthermore, techniques have been adopted to process signals with low activity periods, such as biomedical and industrial sensors. Prior work used least- significant bit first quantization (LSBFQ)...

  • Power efficient analog-to-digital converters using both voltage and time domain information

    Creator:
    Oh, Taehwan
    Abstract:
    As advanced wired and wireless communication systems attempt to achieve higher performance, the demand for high resolution and wide signal bandwidth in their associated ADCs is strongly increased. Recently, time-domain quantization has drawn attention from its scalability in deep submicron CMOS processes. Furthermore, there are several interesting aspects of time-domain...

  • Limitations and optimization of a blind calibration algorithm for nonlinearity in analog to digital converters

    Creator:
    Coker, Brandilyn
    Abstract:
    Analog to digital converters (ADCs) are a critical part of communication between the physical world and the increasingly digital systems humans use every day. ADCs have inherent non-idealities that degrade performance. Nonlinearity is one of the most prevalent non-idealities that designers face. While calibration methods for nonlinearity exist in the...

  • Power-Efficient Design Techniques and Architectures for Scalable Submicron Analog Circuits

    Creator:
    Xu, Yang
    Abstract:
    As the CMOS process scales down to submicron, digital circuit performance improves, while reduced supply voltage and lower transistor intrinsic gain make it difficult to implement analog circuits in a power efficient manner. Therefore, it has become advantageous to shift more analog signal processing functions conventionally realized in voltage (analog)...

  • Energy and area efficient techniques for data converters

    Creator:
    Venkatram, Hariprasath
    Abstract:
    Data converters are ubiquitous building blocks of a signal chain. The rapid increase in communication and connectivity devices presents new avenues for pushing the state of the art analog to digital converters. Techniques for improving resolution, bandwidth, linearity and bit-error rate, while reducing the power, energy and area is the...

  • Efficient use of time information in analog-to-digital converters

    Creator:
    Hu, Yue
    Abstract:
    Time-domain data conversion has recently drawn increased research attention for its highly digital nature in favor of process technology scaling. Also, as the time information being carried by binary voltage, time-domain operation is much less sensitive to voltage noise compared to conventional voltage domain operation. However, for analog-to-digital converter (ADC)...

  • Design techniques for time based data converters

    Creator:
    Gande, Manideep
    Abstract:
    Modern day CMOS processes are characterized by voltage scaling and geometry scaling. Geometry scaling helps reduce gate delays, thereby aiding in the design of data converters which use time based processing. Another artifact of geometry scaling is the increase in complexity of digital circuitry available on traditional analog ICs, as...

    Creator:
    Waters, Allen
    Abstract:
    A procedure for automating the design and layout of analog-to-digital converters (ADCs) is presented. This procedure makes use of the existing synthesis and place-and-route tools that are common in digital circuit design. A method for adding rudimentary analog cells to the standard library is described, allowing the designer to synthesize...
