  • 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...

  • A DC-DC converter architecture for low-power, high-resistance thermoelectric generators for use in body-powered designs

    Creator:
    Miller, Brian A.
    Abstract:
    This thesis presents a low power DC-DC converter suitable for harvesting energy from high impedance thermoelectric generators (TEGs) for the use in body powered electronics. The chip has been fabricated in a 130nm CMOS technology. To meet the power demands of body powered networks, a novel dual-path architecture capable of...

  • Ultra-low energy digital controller for battery-free wireless sensor network nodes

    Creator:
    Nasroullahi, Mohsen
    Abstract:
    This thesis presents a low-energy application specific digital controller for a battery-free 2.4 GHz wireless sensor network (WSN) node. The digital controller has been designed and fabricated in a standard 0.13 μm CMOS and implements a simple protocol for WSNs. Techniques such as supply voltage reduction and power gating have...

  • Power Efficient Hybrid Architecture for High Resolution Analog-to-Digital Converters

    Creator:
    Zhang, Hui
    Abstract:
    Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...

  • Ultra-low-energy transmitters for battery-free wireless sensor networks

    Creator:
    Panitantum, Napong
    Abstract:
    As the number of autonomous data collection applications keep increasing, the demand for wireless sensor networks (WSNs) has seen explosive growth. In this dissertation, an ultra-low-energy WSN transmitter is developed to reduce the energy consumption of sensor nodes in WSNs. With an ultra-low-energy transceiver, it is possible to eliminate the...

  • Noise and Blocker Cancellation Techniques for Power and Area Efficient Wireless Receivers

    Creator:
    Pourbagheri, Saeed
    Abstract:
    The design of mobile wireless devices has always focused on reducing power, area, and cost. This dissertation proposes two techniques that are leveraged to save power and area and therefore cost. The first techniques reduces the noise in the receiver and results in a relaxed power requirement. The second technique...

  • Digital Friendly Continuous-Time Delta-Sigma Analog-to-Digital Converters

    Creator:
    Maghami, Hamidreza
    Abstract:
    Conventional Delta-Sigma analog-to-digital converters (ADCs) utilize operational transconductance amplifiers (OTAs) in their loop filter implementation followed by multi-bit voltage domain quantizers. As CMOS integrated circuit technology scales to smaller geometries, the minimum transistor length and the intrinsic gain of the transistors decrease. Moreover, with process scaling the voltage headroom decreases...

  • Low power receivers for wireless sensor networks

    Creator:
    Ni, Ronghua
    Abstract:
    Wireless sensor networks are becoming important in several monitoring and sensing applications. Ultra low power consumption in the sensor nodes is important for extending the battery life of the nodes. In this dissertation, two low power BFSK receiver architectures are proposed and verified with prototype implementations in silicion. A 2.4...
