Design Challenges

• Wide-frequency spectrum, up to 10MHz
• Symmetrical timing on low-to-high and high-to-low signal edges
• Low input offset to maintain minimal timing error from amplifier output to comparator input
• Minimal power consumption

How High-Speed Comparators Benefit the Systems

• A comparator's fast response time enables the capturing of waveforms with spectrum up to 10MHz and beyond without loss of signal integrity.
• Symmetrical prop delay and rise-fall times of a push-pull output stage enables the arc fault signal to be digitized without distortion and with minimal timing error.
• Low power consumption is necessary due to the always-on nature of arc fault detectors and minimizes power drain on building power systems.
• Low input offset voltage maintains the integrity of an arc fault signature by triggering the comparator output at the precise threshold voltage, rendering an accurate digital waveform for post-processing.
