At such high sampling rate, massively time-interleaved successive-approximation ADC (SAR ADC) architecture has emerged as the dominant solution due to its excellent power efficiency. Several recent works has demonstrated success in achieving high sampling rate.


This thesis focuses on studying how the time domain information can be used to increase the performance of SAR ADCs. To do so, a new SAR ADC architecture

Successive approximation register (SAR) analog-to-digital Converters (ADC) are based on a capacitive digital-to-analog converter (CDAC) (McCreary and Gray, 1975). SAR-Assisted Pipeline ADC Master of Science Thesis For the degree of Master of Science in Microelectronics at Delft University of Technology Iniyavan Elumalai August 21, 2012 Faculty of Electrical Engineering, Mathematics and Computer Science · Delft University of Technology This thesis shows that a SAR and Sigma-Delta ADC can be integrated with the microcontroller. The measurements show good results, but are not perfect. The ADCs can still be im-proved, depending on the desired design parameters. The Sigma-Delta ADC performs better in speed, while the SAR ADC shows a higher precision. There is no clear winner on one module of these sensors – the analog-to-digital converter (ADC) – which translates the (physical) analog signals to the digital domain, where they will be processed.

The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal. It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator.

In this the- sis, a sub-radix-2 SAR ADC is presented with several new contributions. Low-Power High-Performance SAR ADC with Redundancy and Digital Background Calibration by Albert Hsu Ting Chang B.S., Electrical Engineering and Computer Science, University of California, Berkeley (2007) S.M., Electrical Engineering and Computer Science, Massachusetts Institute of Technology (2009) Submitted to the The presented thesis is the design and analysis of an 8-bit successive approximation register (SAR) analog to digital convertor (ADC), designed for low-power applications such as bio-medical implants. First we introduce the general concept of Approximation Register (SAR) ADCs have been gaining more interests in recent years due to their power efficiency and digital friendliness. However, the conversion speed of SAR ADCs is less competitive than other ADC architectures because of its binary search mechanism. integrated SAR ADC with III-V CS (i.e., InGaAs) sampling switch and remaining circuits in CMOS technology.
