  • Analysis and Design of Low Voltage LC Oscillators and their Application to Wireless Sensor Networks

    Creator:
    Guha Roy, Ankur
    Abstract:
    This dissertation focuses on the analysis, design, and application of inductor-capacitor (LC) oscillators for wireless sensor networks (WSNs). First an analysis and design optimization approach for enhanced swing, low power CMOS LC oscillators is presented. A phasor based analysis is used for determining the amplitude and phase noise of these...

  • Design Considerations and Circuit Techniques for Robust Ring-Amplifiers

    Creator:
    Venkatachala, Praveen Kumar
    Abstract:
    Ring amplifiers (ringamps) have shown excellent power efficiency in the latest state-of-the-art analog to digital converters (ADCs). This thesis describes circuit techniques to ensure robust operation of ringamps using standard analog techniques and proportional-integral-derivative(PID) controller analogy. Large-signal and small-signal analysis of a ringamp are performed using simple RC settling and...

  • Design Techniques for Wide-bandwidth Continuous-time Delta-sigma Modulators with Noise-shaping Quantizers

    Creator:
    Dey, Siladitya
    Abstract:
    Noise-shaping multibit quantizers in a ΔΣ modulator offer extra orders of noise shaping without increasing the loop-filter order and without compromising the stability of the modulator. This dissertation presents two new architectures for improving the overall performance of continuous-time ΔΣ modulators using noise-shaped quantizers. The first modulator architecture is motivated...

  • Energy Harvesting and Power Management Integrated Circuits for Self-Sustaining Wearables

    Creator:
    Bose, Soumya
    Abstract:
    Harvesting energy from ambient sources can provide power autonomy to energy efficient electronics and sensors. The last decade has seen a multitude of ways to scavenge energy from various sources like solar, thermal, electromagnetic, electrostatic, piezo-electric and many more. Thermal energy from human body heat is ubiquitous and can be...

  • CMOS Transducers and Programmable Interface Circuits for Resource-Efficient Sensing Applications

    Creator:
    Sengupta, Shaan
    Abstract:
    Modern sensors are complex systems comprising multiple sub-systems such as transducers, analog and mixed-signal interface circuits, digital processing circuits, and packaging. Over the last few decades, innovations in these sub-systems combined with their increased integration in complementary metal-oxide semiconductor (CMOS) processes have led to the rapid growth in sensors for...

  • Development and Implementation of JetNet : A Decentralized Wireless Sensing Protocol

    Creator:
    Goins, Justin B.
    Abstract:
    Modern sensor network applications are often implemented wirelessly in order to lessen installation costs and reduce deployment times. Unfortunately, these wireless sensor network (WSN) nodes must often rely on batteries or energy harvesting techniques in order to sustain their operation and supply the power needed to maintain communication within the...
