Abstract

Analog-to-digital converters (ADCs) are an indispensable part of the digital age we are living in, as they form the interface between physical reality and virtual reality. Higher ADC energy efficiency is the dominant focus of ADC design research due to the high impact of ADC energy consumption to total energy consumption of the systems they are employed in. The energy consumption of an ADC increases with its resolution within a given signal bandwidth, which makes the efficiency of high-resolution ADCs even more important. Although the average energy efficiency of ADCs improved orders of magnitude in the last two decades, the high energy consumption of high-resolution ADCs was still restrictive for a large range of applications. This thesis investigates how the zoom ADC architecture can achieve both high
resolution and high energy efficiency.
