ABSTRACT:
A delay circuit generates delayed signals. The delay circuit includes a delay locked loop having an input terminal coupled to a periodic input signal, the delay locked loop generating one or more delayed periodic signals and a control signal for controlling the time delay between the periodic input signal and the delayed periodic signals. The delay circuit also includes a controlled delay circuit for generating one or more delayed periodic signals. The controlled delay circuit has an input terminal for receiving at least one of the delayed periodic signals from the delay locked loop and a delay control terminal coupled to the control signal from the delay locked loop for controlling the time delay between the delayed periodic input signal received from the delay locked loop and the one or more delayed periodic signals generated by the controlled delay circuit.
