High-Efficiency Power Amplification Techniques for Wireless Transmitters

The low efficiency of existing power amplifiers (PAs) is causing excessive energy consumption in wireless systems. Improving the PA efficiency is therefore of great environmental and economical importance. This thesis address a wide range of advanced PA design methods and novel PA architectures that all contribute to significantly improve the efficiency of PAs for wireless applications. The fir...

A low-power/high-resolution dual-mode analog-to-digital converter for wireless sensor applications

A successive approximation register (SAR) analog-todigital converter (ADC) with an integrating resolution booster (IRB) is proposed and experimentally verified to provide the capability of dual-mode operation, that is, low-power and high-resolution modes. This dual-mode architecture corresponds to a kind of hybrid ADC architecture, combining a low-power SAR ADC and a high-resolution integrating...

Digital Predistortion of Power Amplifiers for Wireless Applications

For my family. iii ACKNOWLEDGEMENTS It is time to draw a period to my PhD endeavor. I feel extremely lucky to meet so many talented people during these years. I am grateful for their friendship, help, encouragement, and support. First, I would like to thank my advisor, Dr. G. Tong Zhou, for providing this opportunity for me to study at Georgia Tech. Her constant encouragement and valuable advic...
