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

摘要

Apparatuses and methods for delaying signals using a delay line are described. An example apparatus includes a controller configured to in a first mode, set a delay length, and, in a second mode, to determine an initial delay. The apparatus further including a delay line circuit coupled to the controller and includes delay elements. Each of the delay elements includes delay gates that are the same type of delay gate. The delay line circuit is configured to, in the first mode propagate a signal through one or more of the delay elements to provide a delayed signal. The delay line circuit is further configured to, in the second mode, propagate a pulse signal through one or more of the delay elements and provide a corresponding output signal from each of the one or more delay elements responsive to the pulse signal reaching an output of the corresponding delay element.

1. An apparatus comprising:
a delay line circuit including a first delay element coupled to a second delay element, the delay line circuit configured to contemporaneously:
propagate a signal in a first loop from the first delay element through the second delay element and back through the first delay element to provide a first delayed signal; andpropagate the signal in a second loop from the first delay element through the second delay element and back through the first delay element to provide a second delayed signal.
