A low-power dynamic comparator for low-offset applications

WebApr 25, 2024 · Abstract: We make the case that in most comparators, offset and noise are determined by a dynamic preamplifier always embedded ahead of a regenerative latch. An analysis of this amplifier follows, from which simple expressions are obtained for input-referred offset and noise bandwidth. Practical circuit methods to compensate offset and … WebA low-offset dynamic comparator using new dynamic offset cancellation technique is proposed. The technology scaling of MOS transistors enables low voltage and low power which decreases the offset voltage and delay of the comparator.
