摘要： A circuit for measuring a transition time of a digital signal may be provided. The circuit comprises a window detector comprising a comparator circuitry arranged for generating a first signal based on comparing said digital signal with a first reference voltage and for generating a second signal based on comparing said digital signal with a second reference voltage. Additionally, the circuit comprises a time-difference-to-digital converter operable for converting a delay between an edge of said first signal and an edge of said second signal into a digital value, said digital value characterizing said transition time of said digital signal.
