Concept Diagram for Time-of-Flight Pulse Detection with Comparator

See more about this use case in How to design with high speed comparators in automotive and industrial systems and our Intro to high speed comparators: ToF distance measurements with LVDS comparator videos.

Design Challenges

How High Speed Comparators Benefit the System

  • Low overdrive dispersion contributes to consistent measurements by reducing pulse amplitude sensitivity.
  • Super-fast propagation delay enables time sensitive measurements to occur.
  • Narrow pulse width detection capability makes it possible to detect objects at farther distances.
  • LVDS and single-ended comparator output options are available depending on downstream device requirements.
