  • A continuous time frequency translating delta Sigma Modulator

    Creator:
    Pulincherry, Anurag
    Abstract:
    This thesis presents a continuous time bandpass delta sigma modulator with frequency translation inside the delta sigma loop. The input IF signal is down converted to baseband after amplification by a low Q, wideband bandpass resonator. The down converted IF signal is digitized by a continuous time, second order lowpass...

  • 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...

  • 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...

  • Error canceling low voltage SAR-ADC

    Creator:
    Wen, Jianping
    Abstract:
    The design of a switched capacitor successive approximation A/D converter is discussed in this thesis. This design adopts a novel capacitance mismatch error cancellation algorithm proposed in references [25, 27]. Detailed charge domain analysis is given in this thesis, which results in an improvement of the proposed algorithm by tracing...

  • Low power high resolution data converter in digital CMOS technology

    Creator:
    Zheng, Zhiliang
    Abstract:
    The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...

  • 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)...

  • Ring amplification for switched capacitor circuits

    Creator:
    Hershberg, Benjamin Poris
    Abstract:
    A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail...

  • Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

    Creator:
    Guerber, Jon
    Abstract:
    In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...
