ABSTRACT:
A comparator with an input stage that selectively powers up an output stage provides an electronic device with a comparator that operates at low power. In an embodiment, an input stage produces a near decision and a true decision, where the near decision is provided to power up an output stage for the comparator to provide an output representative of the true decision.
