An Error Feedback Noise Shaping SAR ADC

Analog-to-digital converters are important blocks in any electronic system which act as a bridge between analog signals and digital processors. The conventional SAR ADC employs a binary search algorithm and has emerged as the most suitable solution for low-power applications, due to its excellent power efficiency. The proposed ADC architecture...

Analysis and Design of a 2.5GS/s 6-bit SAR ADC with a 3-bit/cycle Resolving Scheme

The thesis analyzes the design challenges that arise when developing high-speed ADCs and shows, through an extensive architecture study, that the SAR topology can be used with a sampling rate of 2.5GS/s if asynchronous processing and a multi-bit per cycle approach are adopted. The transistor-level implementation and simulation of a 6-bit SAR ADC...
