  • 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...

  • A fast-settling folded-cascode CMOS operational amplifier

    Creator:
    Abu-Dayeh, Mahmoud A.
    Abstract:
    A fast-settling CMOS operational amplifier using the folded-cascode topology has been designed. The design is based on a theory developed by Yang et al for the optimum settling time of two-pole systems for switched-capacitor applications. The theory states that the two poles are separated by a given factor in order...

  • Power Efficient Architectures for High Accuracy Analog-to-Digital Converters

    Creator:
    Zhang, Yi
    Abstract:
    Incremental ADCs (IADCs) have found wide applications in sensor interface circuitry since, compared to ∆Σ ADCs, they provide low-latency high-accuracy conversion and easy multiplexing among multiple channels. On the other hand, continuous-time ∆Σ ADCs (CTDSM) have been receiving more and more attention as a power-efficient solution in targeting medium to...

  • Power Efficient Architectures for Low Noise Switched-Capacitor Filters and High Accuracy Analog-to-Digital Converters

    Creator:
    Payandehnia, Pedram
    Abstract:
    Filters and data converters are key analog-and-mixed-signal (AMS) building blocks in communication systems, such as software-defined radios and internet-of-things. In this dissertation, novel switched-capacitor filter and analog-to-digital converter (ADC) circuit configurations have been explored which are power efficient and are digital scaling friendly. First, a novel switched-capacitor low-pass filter architecture...

  • Characteriscts of FSO Channel in WIFO

    Creator:
    Wang, songtao
    Abstract:
    With explosive growth of Internet access from smart phones and tablets, increasing bandwidth for WIFI system is badly needed. Depending on two years’ research, we produced a novel communication system called WIFO system, which integrates both RF (Radio Frequency) and FSO (Free Space Optical) techniques. WIFO system can significantly increase...

  • Investigating Time-Digital-Converters for Hardware Security in FPGAs

    Creator:
    Lytikov, Daniil
    Abstract:
    In this comprehensive thesis, we present a series of experiments and findings that highlight the critical importance of TDC Voltage Sensors in the hardware security domain. Our research begins by introducing a novel self-calibrating module, demonstrating its efficiency through preliminary calibration tests. We then delve into the Peak-to-Peak tests, which...

  • New configurations for RF/microwave bandstop and lowpass filters

    Creator:
    Peddibhotla, Harish V.
    Abstract:
    This thesis presents new, compact configurations for RF/microwave bandstop and lowpass filters for embedded passive applications. A simple design methodology is presented for designing the folded-transmission line filters on a microstrip platform. Unlike the conventional stub-loaded filter designs, the proposed folded-line filters will have practical dimensions for a wide range...

  • Active Noise Shaping Analog-to-Digital Data Converters

    Creator:
    Shi, Lukang
    Abstract:
    Successive-approximation-register (SAR) analog-to-digital converters are popular for medium accuracy, medium speed and low power applications, such as in biomedical applications. They have low latency and simple architecture compared with ΔΣ ADCs. This is because of SAR ADCs’ binary searching scheme. Furthermore, SAR ADCs can apply oversampling and noise shaping schemes...
