  • Real Time Self-Interference Cancellation for Wireless Transceivers

    Creator:
    Taylor, Daniel N.
    Abstract:
    With the need for higher spectral efficiency and data rates the rise of simultaneous transmit-and-receive (STAR) radios is becoming increasingly valuable. While many systems employ two separate channels for transmit and receive to double the data speed, this comes at the cost of doubling the RF band. This same performance...

    Creator:
    Borah, Anindita
    Abstract:
    The increasing demand for higher data-rates in spectrum-deficient indoor WiFi networks calls for the adaptation of hybrid systems, consisting of RF and optical wireless channels. The novel hybrid WiFi Free-Space Optical (WIFO) system was introduced to enhance the wireless capacity of indoor WiFi networks. In this thesis, an optical wireless...

  • Millimeter-Wave Wideband Low-Noise Amplifiers in 22FFL Technology

    Creator:
    Gupta, Soumya
    Abstract:
    The deployment of advanced technology standards for 5G and beyond in cellular networks has resulted in interest in integrated circuits (ICs) operating at frequencies above 10GHz. This has sparked research on wideband circuits in commercial low-cost silicon technologies, operating at high RF and mm-wave frequencies. Given the wide range of...

  • High-Resolution mm-wave Digitally Controlled Oscillator in CMOS

    Creator:
    Wang, Yunqi
    Abstract:
    All-digital PLLs promise flexible and precise frequency modulation continous-wave(FMCW) radar signal signal for 77GHz radar applications. Such PLLs require digitally-controlled oscillators(DCO) with wide frequency tuning range and high resolution to address a range of applications and low phase noise requirements. In this thesis, novel resonator structures with ne capacitance/inductance switching...

  • A 400Mb/s 850nm FSO Link based on CMOS Integrated Receiver for Hybrid WiFi and Optical Femtocells

    Creator:
    Chen, Siyuan
    Abstract:
    The increasing demand for higher data-rates is challenging to satisfy with spectrum-deficient indoor WiFi networks. A novel hybrid WiFi Free-Space Optical (WIFO) system has been proposed to enhance the wireless capacity of indoor WiFi networks. In this thesis, an integrated optical wireless receiver is designed and integrated in 65-nm CMOS...

  • Design of 28 GHz Low-Power Phased-Array Receiver Frontend in CMOS

    Creator:
    Garg, Robin
    Abstract:
    This work presents the design and implementation of a low power phased-array receiver frontend at 28 GHz in 65 nm CMOS. The frontend incorporates a low- power low-noise amplifier(LNA) and a passive reflection-type phase shifter (RTPS) capable of providing 360° phase shift with 5-bit phase resolution and low loss variation....

  • UWB Low Power RF System for Localization

    Creator:
    Sheokand, Anoop
    Abstract:
    Real time indoor positioning awareness systems aim to add localization capabilities to upcoming wireless technologies that are quickly becoming an important feature for indoor environment. RF-based impulse-radio ultra-wideband (IR-UWB) is a promising technology for in-door positioning systems due to obstacle penetration capabilities, immunity to multi-path and fading, and high resolution....

  • A 1V 40mA Fast Transient Capless LDO with 7uA Quiescent Current in 180nm CMOS using Ring Amplifier with Adaptive Damping

    Creator:
    Xiao, Bohui
    Abstract:
    Ring amplification has emerged as an efficient technique to drive large capacitive loads in switched capacitor circuits. We propose circuit techniques to demonstrate the first application of a ring amplifier in a non-capacitive feedback system of a LDO. These techniques enable a simple cap-less LDO structure in 180nm CMOS that...

    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...
