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 controller configured to: in a first mode, set a delay length; and in a second mode, determine an initial delay; and a delay line circuit coupled to the controller, the delay line circuit including a plurality of delay elements, wherein each of the plurality of delay elements includes two or more delay gates that are the same type of delay gate, the delay line circuit configured to: in the first mode, propagate a signal through one or more of the plurality of delay elements to provide a delayed signal at an output; and in the second mode, propagate a pulse signal through one or more of the plurality of delay elements and provide a corresponding output signal from each of the one or more of the plurality of delay elements responsive to the pulse signal reaching an output of the corresponding delay element.
