More Information
Summary:A system includes: a power supply; an adaptively biased power event detection comparator; and an adaptive bias circuit for the adaptively biased power event detection comparator. The adaptively biased power event detection comparator is configured to compare a first input corresponding to a voltage level of the power supply with a second input corresponding to a reference voltage. The adaptive bias circuit is configured to increase a bias current for the adaptively biased power event detection comparator based on the voltage level of the power supply decreasing to be closer to the reference voltage.
