Why do we need successive approximation registers ( SAR )?
Raheleh Hedayati Abstract In recent years, there has been a growing need for Successive Approximation Register (SAR) Analog-to-Digital Converter in medical application such as pacemaker. The demand for long battery life-time in these applications poses the requirement for designing ultra-low power SAR ADCs.
How is asynchronous SAR used in 28nm CMOS?
The later 6b 46GS/s ADC in 28nm CMOS employs asynchronous SAR sub-ADC design with back-end meta-stability correction. The measurement results show it achieves sparkle-code error free operation over 1e10 samples in addition to achieving >23GHz bandwidth and 25.2dB SNDR.
Which is thesis work focuses on SAR logic?
This thesis work initially investigates and compares different structures of SAR control logics including the conventional structures and the delay line based controller. Additionally, it focuses on selection of suitable dynamic comparator architecture.
Why are asynchronous SAR sub-ADCs often used?
Furthermore, asynchronous SAR sub-ADCs are often used in these designs to push the sampling rate even further. The well-known sparkle-code issues caused by comparator meta-stability in asynchronous SARs can significantly increase the Bit-Error-Rate (BER) of the transceivers unless power hungry error correction coding are implemented in the system.
