Abstract
A measurement circuit includes a phase detection circuit and delay circuitry. The phase detection circuit compares a first signal to a second signal to generate a first phase difference when the delay circuitry generates the second signal based on the first signal. The phase detection circuit compares the first signal to the second signal to generate a second phase difference when the delay circuitry generates the second signal based on a third signal provided to a signal network. The measurement circuit determines a delay of the signal network based on the first and second phase differences.
