Efficient use of time information in analog-to-digital converters

Creator:: Hu, Yue
Abstract:: Time-domain data conversion has recently drawn increased research attention for its highly digital nature in favor of process technology scaling. Also, as the time information being carried by binary voltage, time-domain operation is much less sensitive to voltage noise compared to conventional voltage domain operation. However, for analog-to-digital converter (ADC)...

Time-based noise-shaping techniques for time-to-digital and analog-to-digital converters

Creator:: Young, Brian LeRoy
Abstract:: In this dissertation, time-based signal processing techniques and their applications in oversampling and noise-shaping data converters are examined. These techniques demonstrate the ability to shift the burden of high performance analog circuits from the compressed voltage-domain to the augmented time-domain. First, the potential of high order noise-shaping and phase-domain feedback...

Wide-bandwidth, high-resolution delta-sigma analog-to-digital converters

Creator:: Zanbaghi, Ramin
Abstract:: There is a significant need in recent mobile communication and wireless broadband systems for high-performance analog-to-digital converters (ADCs) that have wide bandwidth (BW>5-MHz) and high data rate (>100-Mbps). A delta-sigma ADC is recognized as a power-efficient ADC architecture when high resolution (>12-b) is required. This is due to several advantages...

Novel structures for high-speed delta-sigma data converters

Creator:: Chae, Jeong Seok
Abstract:: As CMOS processes keep scaling down devices, the maximum operating frequencies of CMOS devices increase, and hence circuits can process very wide band signals. Moreover, the small physical dimensions of transistors allow the placing of many more blocks into a single chip, including highly accurate analog blocks and complicated digital...

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,...
