A 1-1-1-1 MASH Delta-Sigma ADC using Dynamic Comparator-based OTAs

Low intrinsic transistor gain in nanometer CMOS technologies imposes implementation difficulties of switched-capacitor (SC) circuits based on a conventional OTA used in delta-sigma ADCs. Zero-crossing-based circuits (ZCBCs) have been proposed as replacements for conventional OTAs in SC circuits, b...
