Abstract
A delay-line circuit includes multiple variable-delay circuits and may generate an output signal that is a delayed version of an input signal. A calibration circuit includes an oscillator circuit that may generate an oscillator signal, and may include a replica of at least one of the multiple variable-delay circuits. The calibration circuit may perform an initial calibration of the delay-line circuit and, in response to a completion of the initial calibration, perform a background calibration of the delay-line circuit using the oscillator signal.
