摘要

This paper presents a comparator speed enhancement technique for successive approximation register (SAR) analog-to-digital converter (ADC) under near- and sub-threshold supply voltages. The proposed delayed cross-coupling comparator effectively improves the speed of the comparator while maintaining a good noise performance. This work has been proved by a 350mV 8bit 12MS/s SAR ADC designed in a 65n...
