  • Feedforward noise cancellation techniques

    Creator:
    Yang, Bangda
    Abstract:
    Supply noise is one of the major considerations in almost all analog building blocks. In the past, adequate supply rejection is usually achieved with circuit isolation or excess capacitive coupling. However, this brute force method requires large silicon area and degrades feedback bandwidth. In this study, a method of enhancing...

  • Liquid-gated carbon nanotube transistor noise sources and sensitivity limits

    Creator:
    Sharf, Tal
    Abstract:
    Low-dimensional electronic materials offer a platform to observe biological processes with unprecedented spatial and temporal resolution. Carbon nanotubes (CNTs) are the closest physical analog to an ideal 1D system and can be scaled and integrated into multiplexed electronic circuitry. The molecular structure of a CNT is also biocompatible, making them...

  • Low-power techniques for supply-noise mitigation in phase-locked loops

    Creator:
    Arakali, Abhijith
    Abstract:
    Modern day digital systems employ frequency synthesizers to provide a common clock to the system. They are undergoing large scale integration due to which, mitigation of the effect of noise on power supply has become a major design consideration in clocking circuits. Rapid scaling of CMOS technology mandates the design...

    Creator:
    Kesharwani, Divya
    Abstract:
    Various applications like wireless UWB communication, fast data acquisition systems and digital storage oscilloscopes needs ADCs with instantaneous input signal bandwidth from 0.1-40 GigaHertz range with 6-10 bits of resolution -- a challenging task and an impressive goal to achieve. Flash ADCs have been conventionally employed to achieve these goals...

  • Architectural compensation techniques for analog inaccuracies in delta-sigma analog-to-digital converters, Architectural compensation techniques for analog inaccuracies in ΔΣanalog-to-digital converters

    Creator:
    Maghari, Nima
    Abstract:
    Delta-sigma analog-to-digital converters (ADCs) are suitable for many applications due to several advantages such as relaxed anti-aliasing filter, high signal-to noise and distortion ratio (SNDR) and most important of all, reduced sensitivity to analog imperfections.This thesis introduces several structures to overcome loop imperfections and stability issues in delta-sigma modulators. First,...

  • Pattern discovery in noisy images

    Creator:
    Dhamodaran, Sharath Kumar
    Abstract:
    The Focused Ion Beam (FIB) tool is a versatile instrument for nano-machining in circuit editing. Circuit editing is one of the most important steps in the design of an electronic circuit on a chip. Circuit editing can be improved by imaging of silicon plates and analyzing the resultant images. However...

  • Decoding channel coded higher-order QAM signals over Gaussian and Rayleigh fading channels

    Creator:
    Yang, Yun
    Abstract:
    In modern digital communication systems, error correction codes (ECC) are widely used and play an important role. The main effect of ECCs is to reduce the transmission error caused by channel noise, thereby protecting data and increasing the quality of information transmission. In addition, high spectral efficiency is desired in...

  • Performance enhancement techniques for low power digital phase locked loops

    Creator:
    Elshazly, Amr
    Abstract:
    Desire for low-power, high performance computing has been at core of the symbiotic union between digital circuits and CMOS scaling. While digital circuit performance improves with device scaling, analog circuits have not gained these benefits. As a result, it has become necessary to leverage increased digital circuit performance to mitigate...

    Creator:
    Yu, Wenhuan
    Abstract:
    This dissertation presents an incremental analog-to-digital converter (ADC) with digital digital-to-analog converter (DAC) mismatch correction. A theoretical time-domain analysis technique was developed to predict the noise performance of the incremental ADC, and a new optimization technique was proposed to minimize the output noise. In the calibration mode, the incremental ADC...

    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...
