Sequential activation delay line circuits and methods

摘要

Delay line circuits and methods include a series of unit delay cells, a respective one of which includes an input and an output that are sequentially connected such that an output of a preceding unit delay cell is connected to an input of a succeeding unit delay cell. At least two of the unit delay cells in the series are sequentially activated in response to an activation signal. The sequential activation may be performed by a control circuit that is connected to the series of unit delay cells.
