Abstract

Power monitoring circuitry. In some embodiments, comparator circuitry may be configured to receive a first voltage value and a second voltage value, and to identify the greater of the first and second voltage values. Selector circuitry coupled to the comparator circuitry may be configured to power one or more components within the comparator circuitry with a supply voltage corresponding to the greater voltage value. In other embodiments, a method may include identifying, via a comparator, the largest among a plurality of voltage values, and powering one or more logic components within the comparator with the identified voltage value.
