  • Duty-cycle controlled switched resistor techniques for continuously tunable, low-voltage circuits

    Creator:
    Kurahashi, Peter
    Abstract:
    A duty-cycle controlled switched resistor is a tunable resistive element that uses pulse width modulation as the method of tuning. This thesis will describe the operation of switched resistors and propose several circuit architectures that are well suited to the use of switched resistors. These architectures include filters, mixers, and...

  • Low voltage techniques for pipelined analog-to-digital converters

    Creator:
    Carnes, Joshua Kenneth
    Abstract:
    To realize pipelined ADCs in deep-submicron processes, low voltage techniques must be developed to work around problems created by limited supply voltages such as the floating switch dead zone, reduced SNR, and reduced OpAmp performance. This thesis analyzes standard and low voltage design issues for pipelined ADCs and proposes a...

  • Low voltage switched capacitor circuits for lowpass and bandpass [delta sigma] converters

    Creator:
    Keskin, Mustafa
    Abstract:
    The most accurate method for performing analog signal processing in MOS (metal-oxide-semiconductor) integrated circuits is through the use of switched-capacitor circuits. A switched-capacitor circuit operates as a discrete-time signal processor. These circuits have been used in a variety of applications, such as filters, gain stages, voltage-controlled oscillators, and modulators. A...

  • Continuous time input pipeline ADCs

    Creator:
    Gubbins, David Patrick
    Abstract:
    Analog-to-digital converters (ADCs) convert analog continuous time signals into discrete time, digital format. One precondition that must be met for conventional nyquist rate ADCs is that the input signal must be suitably band-limited to an input bandwidth less than the nyquist frequency. This mandates expensive anti-alias filters which contribute to...

  • Low-voltage pipeline A/D converter

    Creator:
    Wu, Lei
    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor (SC) circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low voltage conditions. There exist three techniques to solve the problem, but with their...

  • Low power design techniques for analog-to-digital converters in submicron CMOS

    Creator:
    Musah, Tawfiq
    Abstract:
    Advances in process technologies have led to the development of low-power high speed digital signal processing blocks that occupy small areas. These advances are critical in the development of portable electronic devices with small feature size and long battery life. However, the design of analog and mixed-signal building blocks, especially...

  • 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...

    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...

    Creator:
    Greenley, Brandon Royce
    Abstract:
    The design of mixed-signal integrated circuits has evolved from simple analog and digital circuits operating on the same silicon substrate to the point that now we have complete system on a chip solutions for communication systems. The levels of integration needed to remain cost effective in today's integrated circuit (IC)...

  • Design techniques for PVT tolerant phase-locked loops

    Creator:
    Wu, Ting
    Abstract:
    The continued scaling of deep-submicron CMOS technology enables low-voltage high-frequency phase-locked loops (PLLs) to be fully integrated in complex mixed-signal systems. However, fluctuations due to the manufacturing process and variations in environmental conditions, such as supply voltage and temperature, are also significantly increased. As a result, the performance of PLLs...
