Abstract: This letter presents a two-step SAR ADC that uses coarse and fine comparators with dedicated SAR logics and asynchronous clock generators for each comparator to increase the energy ...

Abstract: This article presents a single-channel 4-GS/s 8-bit hybrid-domain analog-to-digital converter (ADC) implemented in a 28-nm CMOS process. The proposed 8-bit ADC combines a 3-bit ...
