Propagation Delay
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Propagation delay is the time required for a signal to travel from the input of a logic gate or circuit to its output after a change occurs. It limits the maximum operating frequency of digital systems.
Example in context
“The propagation delay of each gate in the chain must be summed to verify that the clock period exceeds the total path delay.”
“Zincirdeki her bir kapının yayılma gecikmesi, saat periyodunun toplam yol gecikmesini aştığını doğrulamak için toplanmalıdır.”
Where engineers use it
Propagation delay is critical in synchronous circuits to ensure setup and hold times are met. Engineers analyze it during timing analysis to avoid race conditions and meet clock frequency targets.
Synonyms: gate delay, transition delay
Practice: can you use “Propagation Delay” at work?
You are given a chain of three inverters with specified propagation delays. Determine the minimum clock period needed to avoid timing violations.
Show a model answer
“Calculate the maximum clock frequency given the propagation delays in this path.”
