Abstract
A supply voltage detector of an integrated circuit is able to detect the state of a supply voltage upon startup with both high-speed and low overall power consumption. The supply voltage detector includes a comparator that generates an output voltage based on the current state of the supply voltage. The comparator includes a startup current booster that generates a supplemental current for the comparator while the supply voltage is ramping up. The start of current booster stops generating the supplemental current when the supply voltage reaches the expected steady-state value or a selected fraction or portion of the expected steady-state value.
