Apparatuses and methods for delaying signals using a delay line with homogenous architecture and integrated measure initialization circuitry

A method, comprising:

• configuring a delay line circuit of a delay-locked loop to a first configuration during a first mode;
• in the first mode:
• propagating a signal along a first signal path through one or more of a plurality of delay elements of the delay line circuit, wherein each of the plurality of delay elements includes a corresponding two or more delay gates, wherein each of the two or more delay gates are the same type of delay gate;
• and
• providing a delayed signal from the delay line circuit;
• configuring the delay line circuit to a second configuration during a second mode;
• and
• in the second mode:
• propagating a pulse signal along a second signal path through one or more of the plurality of delay elements;
• providing a corresponding asserted output signal from one or more of the plurality of delay elements responsive to the pulse signal reaching an output of the corresponding delay element;
• and
• determining an initial delay based on a the asserted output signals.

A method, comprising:

• configuring a first delay element and a second delay element to a first configuration during a first mode;
• in the first mode:
• receiving a signal at a first delay gate the first delay element;
• providing the signal from the first delay gate of the first delay element through a first delay gate and a second delay gate of the second delay element to a second delay gate of the first delay element;
• and
• outputting a delayed signal from the second delay gate of the first delay element based on the signal received at the second delay gate of the first delay element, wherein the first delay gate and the second delay gate of the first delay element and the first delay gate and the second delay gate of the second delay element include a same delay gate type;
• configuring the first delay element and the second delay element to operate in a second mode based on the control signals having a second configuration;
• and
• in the second mode:
• providing a pulse signal from a third delay gate of the first delay element to a fourth delay gate of the first delay element and to a third delay gate of a second delay element;
• outputting a first output signal from the fourth delay gate of the first delay element to a controller and to the third delay gate of the second delay element;
• and
• outputting a second output signal from the fourth delay gate of the second delay element to the controller, wherein the controller determines an initial delay based on the first output signal and the second output signal.
