A 1-1-1-1 MASH Delta-Sigma Modulator With Dynamic Comparator-Based OTAs

A dynamic comparator-based OTA is introduced as a replacement for a conventional OTA. It performs charge transfer in a switched-capacitor circuit by repeatedly evaluating the polarity of the differential input using a dynamic clocked comparator and injecting current pulses at the output to move the...
